SOCIALIZATION ASSIGNMENT Example | Topics and Well Written Essays - 250 words
SOCIALIZATION - Assignment Example It plays a significant role in upholding womenââ¬â¢s rights and freedom such as womenââ¬â¢s sufferings (Schmidt, Shelley and Bardes 9). Furthermore, my parents also believe in the leftists political arguments. The left political ideology has a broad social and cultural influence, which considerably contributed to my political stance. The left principles subscribe to freedom of speech that greatly endorses dissemination of extensive information through the media. Furthermore, it plays an important role in attaining societal equality. It aims at establishing an ideal society without disparities on social classes. The left ideology intents include the relocation of resources through a welfare State. Primarily, this belief engages in communal unity, respect, co-existence as well as collective functioning. Currently, my opinions as a leftist have greatly changed over time. This is attributed to the influence of socialization agents such as peer groups, media, family, religious institutions and schools. Religious institutions have altered my perceptions in support of left beliefs by condemning some of leftistsââ¬â¢ policies, such as legalizing abortion, as being evil and against humanity. The right-wing politics are presented as ideologies that promote right to private ownership by the media. Although there are arguments for right ideologies, I declined to support them following claims by activist that right systems allege to proliferate community advancement while they are tainted with the intention of enriching a few. From these claims, I am of the opinion that integration of these two ideologies would be most

Convergence Law and Its Relevance Essay Example | Topics and Well Written Essays - 1250 words
Convergence Law and Its Relevance - Essay Example As such, the paper discusses the multiple factors that have had an influence on the formation and convergence of European law. Primarily, this convergence is the result of the necessity of uniformism that has been demanded since the European Union first formed. As a result, integrations have taken place based on the interpretation of individual laws, as well as entire constitutional understanding. As the idea of citizenship has been defined to incorporate an individual into the greater whole of the European Union, likewise individual interpretations of existing law has been forced to be understood, fabricated, and analyzed through the very same constructs. As a vehicle for understanding this concept, Tryfonadou introduces the topic of free movement of persons and free movement of goods as it evolved in the late 1990ââ¬â¢s through early 2000ââ¬â¢s. Perhaps, one of the best examples of this convergence can be seen in what Tryfonadou describes as the ââ¬Å"restrictionâ⬠and ââ¬Å"discriminationâ⬠of free movement law. ... persons, existing laws have made an attempt, according to Tryfonadou, to juxtapose the two and come to a common understanding and definition in the scope of the laws. (1) The author goes on to explain to the reader the differences between subsidiarity law principles and proportionality principles. Subsidiarity requires that the community adopt the legislation only if it is a requirement to achieve a given object. Accordingly, proportionality requires that the burden of the lawââ¬â¢s enactment be proportionally weighted so as not to be too heavy with relation to the objective that is trying to be achieved. An unavoidable facet of the European Unionââ¬â¢s construction requires that one understand and realize the importance of the many different legal systems that make up its component parts, as well as how each of these systems begins to find a certain commonality within the law, i.e. the convergence principle that Tryfonadou has written. Due to the additional fact that the Europ ean Union is made up of a multiplicity of differing legal systems of its member states, recognition of the defining legal principles which each system espouse combined with the aforementioned principles of subsidiarity and proportionality lead invariably to a form of legal diversity. In short, even though the diverse systems of law that are extant within the European Union espouse similar legal views on a variety of different and diverse topics (i.e. Roman, Anglo-Saxon, and Scandinavian law) all have a host of commonalities with which to draw from. Regardless, the formation of the European Union has provided a type of centrifugal force that has worked to mold each of the aforementioned member states particular understanding into a more common and generally accepted form of jurisprudence which had
Terrorism on September 11, 2001 Essay Example for Free
Terrorism on September 11, 2001 Essay Terrorism is no vague concept but a modern danger and growing concern throughout the world. With the peak of violence seen on September 11, 2001 and the subsequent attacks experienced throughout the world following that attack, the United States awareness and reaction to terrorism and terrorist acts has changed. In an ideological war with no end in sight the way in which America fights the war on terror will help determine the eventual outcome. In his report, Unconquerable Nation, terrorism analyst Brian Michael Jenkins attempts to provide background and a deeper understanding of the threat faced by the United States in the coming years from al Qaeda and similar groups. This information teamed with advice and analysis gleaned from decades of terrorism research, lay out a plan for combating terrorism through deeper means and deeper understanding of the enemy. As Jenkins explains is his introductory chapter, a five-point philosophy of war must be employed not only by the government in the war on terror but also supported and carried by the average citizen. The five points are a necessity of knowing the enemy, mobilization of individual courage and commitment to the necessary good, psychological strength, an understanding and commitment to the longevity of the mission, and embracing ââ¬Å"liberty as the source and sustenance of securityâ⬠(2006, p. 5). Among some of the flaws in the current campaign is the failure to perform many of these points, chief among them is a lack of understanding of the enemy and the reality of the time necessary to defeat such a foe. Brian Michael Jenkins has been part of terrorism research and strategy from the beginning, when in 1972 the U. S. first began to take a look at terrorism as a distinct and increasingly dangerous risk (p. 6). As he notes, the Lod Airport massacre in Israel and the murder of Olympic athletes in Munich in 1972 led to the creation of the Cabinet Committee to Combat Terrorism (p. 7). However, terrorism has continued to evolve over the past several decades as the terrorist ideology has shifted from a strictly political standpoint into the arena of religious (p. 8). Conventionally defined as ââ¬Å"a small, artificially defined segment of political violenceâ⬠(Jenkins, 2006, p. 8), it has grown to be most visible in recent years as a mix of skewed religious ideologies and political unrest viewed through centuries of historical and theological unrest. In the 1980s the threat from terrorism grew outside the arena of simply a political vehicle. Where once terrorist acts were committed to gain visibility and understanding of the group and their demands, the attacks had now become more bloody and indiscriminate as the terrorists are not interested in image. Jenkins explains that, ââ¬Å"today, many terrorists want a lot of people watching and a lot of people deadâ⬠(2006, p. 9). With the increase of senseless, casualty-heavy violence fears over what methods they will employ have increased. In the 1990s, after the collapse of the Soviet Union a general sense of fear began to permeate among international and political analysts (p. 146). The United States and other western countries began preparing for the worst, as predictions were made on nuclear proliferation, the diversion of the Soviet Unionââ¬â¢s heavy arsenal to terrorist groups and unsympathetic countries (p. 147-148). However, none of these fears has yet come to tangible proof. While on 9/11, terrorists were able to deal the largest blow to the United States through conventional terrorist methods of attack, their bombs were neither nuclear or biological; their infiltration into society and subsequent hijacking were done using conventional means and bombs (p. 149). Primary among, Jenkins points is the understanding of al Qaeda and related jihadist groups in waging a successful campaign against terrorism. Terrorists today arenââ¬â¢t the same as traditional guerilla militias or the terrorists of the 1970s. ââ¬Å"The enemies we face have changed fundamentallyâ⬠(Jenkins, 2006, p. 14). Though the current U. S. led efforts to subdue and eradicate al Qaeda and related groups have been successful in driving them underground, they have not addressed the root of the terrorist discourse or stemmed recruitment or what Jenkins calls the political war (p. 14). In ignoring the current implications and ideology of al Qaeda and like-minded terrorists the U. S. is counteracting its own progress. The concept of jihad, the driving force behind al Qaeda, has been elevated, ââ¬Å"from a struggle within oneââ¬â¢s soul to an unlimited war against the Westâ⬠(p. 23). Their grievances with the West, as espoused by Osama bin Laden and his brothers in arms, are both valid and unattainable. One of the root causes noted by bin Laden and his followers include the treatment of Palestine by Israel which the U. S. is seen as supporting through their support of Israel. This could and, according to Jenkins, should be addressed as it is a ââ¬Å"nobleâ⬠cause (p. 125). However, many of their grievances such as the presence of the U. S. in the Middle-East, Saudi Arabia, a saturation of Western culture as a destructive factor in Islam are unattainable goals. Jenkins implies and I agree, that the demands are unattainable by design and therefore supportive of a never-ending jihad. Those who believed that the war on terrorism would begin and end with the war in Iraq were only half right. While of strategic and ideological importance, Iraq has been both an overly dominant and distracting force in the overall war on terrorism. I agree with Jenkins assessment that the conflict will only reach another stage with the withdrawal from Iraq and whether viewed with defeat or victory the withdrawal will usher in a new stage in an ongoing conflict. I agree wholeheartedly with Jenkins assessment that, ââ¬Å"we are still closer to the beginning then the end of what is likely to be a very long campaignâ⬠(p/ 176). In fighting a political war against al Qaeda and other jihadists, the U. S. would be most effective in trying to stem recruitment, prevent the spreading of their ideology by promoting alternatives and education on religion (p. 125). By using measures to halt recruitment and reeducate detainees, the U. S. would see more long term results. Many of the tactics used so far like the fall of the Taliban and closing of training camps in Afghanistan, thwarted attacks, and disrupted funding (pp. 27-29), while important do not dispel the groupââ¬â¢s danger. As Jenkins explains, they have adapted to the new limitations and not knowing the actual size of the enemy it is difficult to assess the true danger and actual gains (p. 27). The jihadistââ¬â¢s real weapon against the U. S. is ideological, ââ¬Å"Armed forces alone cannot win this war. The real battle is ideologicalâ⬠(Jenkins, 2006, p. 120). A loss of capital hasnââ¬â¢t prevented attacks since 9/11 or halted recruitment. In the environment created by the U. S. ââ¬â¢s continued presence in Iraq, the jihadists have attempted to seize an opportunity to use discontent to build their numbers. The U. S. has to fight this as well. The U. S. and other countries fighting the war on terrorism have to discredit al Qaedaââ¬â¢s message and to use their extremism against them. Jihadistsââ¬â¢ beliefs are the minority, ââ¬Å"to many Muslims, even those angered by U. S. policies, bin Laden is a crackpotâ⬠(p. 107). Still to some he speaks the truth and even changing the way in which believers are handled would be effective in the long run in defeating the threat. By trying to change the thinking and treatment of detainees, the U. S. and other governments can prevent future acts of terrorism. By working with willing defectors and possible converts, the U. S. could stem their flow of willing bodies, which is their greatest weapon, as Jenkins explains and I agree, ââ¬Å"political warfare accepts no for as having irrevocably crossed a lineâ⬠(p. 122). If the U. S. government and itââ¬â¢s allies write off the discontent of the recruitment population they run the risk of alienating a whole new generation of terrorist fighters. Jihadââ¬â¢s strongest weapon is its connection to the people; recruiters are able to recognize and weed out the committed and able to manipulate religious belief. Islam is used as a unifying factor by these terrorist groups, they see unity in the Muslim world as an outcome of jihad (p. 107). Increased modes of communication such as the internet and intense organization have allowed for a broader reach in the jihadist message. Their leaders are in for the long haul, ââ¬Å"al Qaeda will not quit its leaders have no alternativesâ⬠(p. 38). By fighting the root causes of the movement and creating disillusionment and doubt in its followers, though more time intensive, the West will create a better future. As long as jihadist ideology is treated as outside the realm of reasonable understanding, it will not be defeated. As Jenkins pointedly explains, ââ¬Å"their mindsets and their concepts of fighting are foreign to us, but they make sense in the context of their beliefs and circumstancesâ⬠(p. 60). Through understanding, the war on terrorism will have its greatest victories. It canââ¬â¢t be treated or viewed like a conventional war, the enemy is not another country or a distinct leader but a mindset bred from circumstance and perverted ideals. So, first and foremost we must battle against the mindset. Countries like Yemen, Singapore, and Saudi Arabia have had success with religious counseling and debate with detainees (p. 130-131). Why doesnââ¬â¢t the U. S. do the same? Instead their have been indeterminate detainments, isolation, and endless interrogation (p. 132). Torture as a means of interrogation, something thought to be beneath American values has been not only practiced by defended. This is not the way to show and maintain our values in the face of a belief based insurgency. We have to learn from other countries examples and Jenkins proposes acceptance of even our imperfect allies, particularly Russia and Pakistan (p. 134). I agree with Jenkins in his assessment of realizing and accepting the risks and realities of this type of campaign is paramount in a publicly advocated and successful war (p. 153). War does not come without risk or with guaranteed successes, there will be discouragements as not every attack can be foreseen and prevented but conscientious persistence is a must.

Aspects of British Culture
Aspects of British Culture Aspects of British Culture What is culture? Is it the language we speak, overall ethnicity in a region, or the simple customs of a daily routine? Culture is something we are all a part of whether we like it or not. Your family may have certain customs and routines. This is culture. In this research paper I will be analyzing British culture in four categories: history, ethnicity, customs, and also the future direction of British Culture. How did Britain become so rich in culture? Well Britain certainly did not just appear one day. The name of the country and the term ââ¬Å"Englishâ⬠derive from the Old English word for one of the three Germanic Peoples that invaded the British Isles in the 5th century (Countries and Their Cultures). The Angles ââ¬Å"Britainâ⬠and ââ¬Å"Britishâ⬠derive from a Roman Term for the inhabitants (Countries and Their Cultures). In fact, written records of British History do not exist until the arrival of the Romans (J.P. Dommerville). Before the arrival of the Romans, there is only archaeological evidence of Britainââ¬â¢s inhabitants (J.P. Sommerville). The earliest inhabitants of Britain for whom there is compelling evidence are bands of hunters living in Southern and Western England during the Hoxnian (J.P. Sommerville). Many peoples make up the rich history of British Culture. There were many immigrants that came to found The United Kingdom. Their genes still walk th e grounds today. Just like America this country was founded, and made by immigrants from many different backgrounds. Like many cultures, there are different peoples whom make up the general ethnicity. British Culture is no exception to this understanding. Britain or the U.K. known to others is located in Western Europe, islands including the northern one-sixth of the island of Ireland between the North Atlantic Ocean, and the North Sea, northwest of France (UK Language, Culture, Customs and Etiquette). The capital of the United Kingdom is London (UK Language, Culture, Customs and Etiquette). The population is roughly 60, 766, 238 people; with an ethnic make-up of White, Black, Indian, Pakistani, Mixed, and Other (UK Language, Culture, Customs and Etiquette). The White Population is composed of: 83.6% English, 8.6% Scottish, 4.9% Welsh, and 2.9% Northern Irish (UK Language, Culture, Customs and Etiquette). The other ethnic populations are composed of: 2% Black, 1.8% Indian, 1.3% Pakistani, 1.2% Mixed, and 1.6% Other (UK Language, Culture, Customs and Etiquette). As you can see, all of these dif ferent ethnicities will definitely impact culture. So what customs will follow this diverse cultural background? Many people may assume that British Culture is defined with scones and tea, or the rich writings of Shakespeare; however it is not like this at all. There are many customs that British people practice, that Americans or any other type of nationality may find odd. Many customs are associated with the annual climate, and British Culture is once again no exception. The annual climate of the United Kingdom has temperatures that are moderated by southwest winds over the North Atlantic Current, and more than one-half of the days are overcast (UK Language, Culture, Customs and Etiquette). The U.K. is also home to a constitutional monarchy (UK Language, Culture, Customs and Etiquette). Although there is no defined official language due to the diverse cultural background, the primary language is English (UK Language, Culture, Customs and Etiquette). About 70% of the population speaks English (UK Language, Culture, Customs and Etiquette). Other languages that are frequently spoken include: Welsh, Irish, Ulster Scots, Cornish, Gaelic, and British Sign Language (UK Language, Culture, Customs and Etiquette). The United Kingdom is comprised of four countries: England, Scotland, Wales, and Northern Ireland (UK Language, Culture, Customs and Etiquette). Now all of these countries share a common thing, and that is to address a person from a country properly. For instance, English and British do not mean the same thing (UK Language, Culture, Customs and Etiquette). The term ââ¬Å"Britishâ⬠, denotes someone who is from England, Scotland, Wales, or Northern Ireland (UK Language, Culture, Customs and Etiquette). The term ââ¬Å"Englishâ⬠, refers to people from England, Scotland, Wales, and Northern Ireland (UK Language, Culture, Customs and Etiquette). People from different countries want to be known for what they are; another example is people from Scotland are identified as ââ¬Å"Scotsâ⬠. People from Wales are identified as ââ¬Å"Welshâ⬠. People fr om Northern Ireland are identified as ââ¬Å"Irishâ⬠(UK Language, Culture, Customs and Etiquette). The Class System As many people can depict from their prior knowledge, British Culture has been known for their many kings and queens, knights, priests etc., however British Culture has changed. Yes, Britain still has and practices a monarchy form of government, but the class system is somewhat complex. Class is no longer simply about wealth or where one lives; the British are able to assume someoneââ¬â¢s class through a number of complex variables (UK Language, Culture, Customs and Etiquette). Brits focus on demeanor, accents, manners, and compartment to determine and factor a class system (UK Language, Culture, Customs and Etiquette). Brits are also facing a very diverse culture, therefore making it difficult to define someone British (UK Language, Culture, Customs and Etiquette). Human Interactions In the United Kingdom, human interaction is of utmost importance. You do not want to offend anyone who is a native, or move there and ignore a cultureââ¬â¢s customs. Most of Britainââ¬â¢s population enjoys sport and leisure activities (Currency). In one way or another, Britainââ¬â¢s population is involved in sports or leisurely activities whether as a participant or a spectator (Currency). A difficult thing to grasp might be understanding a regional dialect, or accent (Currency). The British have been historically known for their ââ¬Å"stiff upper lipâ⬠, and ââ¬Å"blitz spiritâ⬠as demonstrated during the German bombings of World War II (UK Language, Culture, Customs and Etiquette). This grin and bear it attitude in the face of adversity of embarrassment lives on today (UK Language, Culture, Customs and Etiquette). In common interaction Brits do not choose to show strong emotion when engaged in conversation (UK Language, Culture, Customs and Etiquette). This i s not because of their lack to feel, or rudeness; they simply just wish not to display this in public (UK Language, Culture, Customs and Etiquette). In the U. K. manners are all about a reduction of violence between people (Currency). Religion Religion is a large part of British Culture. Due to the large diversity among British peoples, religion is present in many forms and beliefs. Christianity is a popular religion with many denominations such as: Anglican, Roman Catholic, Presbyterian, Baptist, and also Methodist. Roughly 71.6% of British population is Christian and belongs to some Christian Denomination (UK Language, Culture, Customs and Etiquette). Other religious practices involved with British Culture are Muslim, Hindu, Other, and unspecified or none. Roughly 2.7% are Muslim, 1% are Hindu, 1.6% are other, and 23.1% are identified as an unspecified or none (UK Language, Culture, Customs and Etiquette). What does the future hold in store for British Culture? As we can see in the modern day culture is always changing. Culture is definitely different then it was in the seventeenth-century. So what does the future hold in store for British Culture? Well, according to Vikki Heywood (CBE, Chair of the RSA, and formerly executive director of the Royal Shakespeare Company), exclaimed that the commissions brought a wealth of experience in the arts and cultural sectors to the task (Kingââ¬â¢s College London). Heywood also proceeds to exclaim that there are five key goals for the future of the cultural and creative industries (Kingââ¬â¢s College London). The five goals focus on creating, harnessing, and maintaining a rich cultural and creative ecosystem that contributes to the economic and social success of all areas of the country (Kingââ¬â¢s College London). In 2013, the cultural and creative industries provided around 77 billion sterling pounds of added value to the global economy (Kingââ¬â¢s College London). So what does all of this mean? Well the answer is quite simple. The government, cultural, and creative industries need to work together to ensure that everyone has equal access to a rich cultural education, and that conditions are in place for culture, and creativity to play their part in economic success (Kingââ¬â¢s College London). In conclusion, I would say after doing somewhat extensive research, culture is a broad term. There are so many things that impact culture. All cultures are different; however I feel that I have learned an enormous amount of details from writing this paper. I do feel like I have achieved my goal of analyzing four categories or aspects of British Culture. I also feel like I have effectively covered the history, ethnicity, customs, and future direction of British Culture. British Culture is very rich in history, ethnicity, customs, and also future direction. As of right now it looks as if British Culture is evolving into a very rich and unique position of power.

Before The Law :: Short Story Stories Essays
Before The Law BEFORE THE LAW stands a doorkeeper. To this doorkeeper there comes a man from the country and prays for admittance to the Law. But the doorkeeper says that he cannot grant admittance at the moment. The man thinks it over and then asks if he will be allowed in later. "It is possible," says the doorkeeper, "but not at the moment." Since the gate stands open, as usual, and the doorkeeper steps to one side, the man stoops to peer through the gateway into the interior. Observing that, the doorkeeper laughs and says: "If you are so drawn to it, 'just try to go in despite my veto. But take note: I am powerful. And I am only the least of the doorkeepers. From hall to hall there is one doorkeeper after another, each more powerful than the last. The third doorkeeper is already so terrible that even I cannot bear to look at him." These are difficulties the man from the country has not expected; the Law, he thinks, should surely be accessible at all times and to everyone, but as he now takes a c loser look at the doorkeeper in his fur coat, with his big sharp nose and long, thin, black Tartar beard, he decides that it is better to wait until he gets permission to enter. The doorkeeper gives him a stool and lets him sit down at one side of the door. There he sits for days and years. He makes many attempts to be admitted, and wearies the doorkeeper by his importunity. The doorkeeper frequently has little interviews with him, asking him questions about his home and many other things, but the questions are put indifferently, as great lords put them, and always finish with the statement that he cannot be let in yet. The man, who has furnished himself with many things for his journey, sacrifices all he has, however valuable, to bribe the doorkeeper. The doorkeeper accepts everything, but always with the remark: "I am only taking it to keep you from thinking you have omitted anything." During these many years the man fixes his attention almost continuously on the doorkeeper. He forgets the other doorkeepers, and this first one seems to him the sole obstacle preventing access to the Law. He curses his bad luck, in his early years boldly and loudly; later, as he grows old, he only grumbles to himself.

Language Development in Hearing-impaired Children Essay -- Linguistics
This had to be the hardest paper that I have written here at Ashford. I think a lot had to do with finding four articles that I could really relate to. Well, then again finding the articles that interested me the most in one of the following areas: cognitive development, language development, social development, or memory and the brain in children and infants. Most students would say that this is easy, however, my situation is not like most students. I have a 6 year old little girl, named Racine, that is my true inspiration. She is the reason why I am here at Ashford and deciding my major. The reason why I bring my daughter up in this paper is because all of the area I have to write about really concern her. Racine is hearing impaired and will most likely be deaf by the age of 10 years old. This is very said for our family. However, the hardest part is not her losing her hearing but it is everything else with her learning. Racine has all of the above issues we are suppose to write our paper about. However, her two major issues , along with the hearing loss, are cognitive development and language development. With you knowing a little about Racine, I would like to go a little out of the box. What I mean by this is that I have read all kinds of articles and research on these two different developmental areas and there really is not a lot dealing with hearing loss associated with them. Within doing my research for this paper I have found that children who experience hearing loss tend to speak in three specific ways. These ways includes American Sign Language, either using aural- oral communication, or simultaneous. Children with hearing loss have to develop communication skills through the value of their eyes rather than the... ... from http://www.wrongdiagnosis.com/medical/hearing_impairment.htm Causes of Hearing Loss in Children.

Recrystallization of Acetanilide Using Water as Solvent Essay
Abstract Recrystallization is a technique used to purify organic solids. This method involves dissolving of a solute in a solvent and inciting the solute to produce a precipitate from a solution. In this experiment, acetic anhydride was added to the mixture of 2mL aniline and 20mL of distilled water. The mixture was cooled in an ice bath and filtered through filter paper resulting to the crude acetanilide. The pure acetanilide was then produced by the filtered solution of crude acetanilide and recrystallizing solvent. Choosing of the recrystallizing solvent was done by placing a small amount of pure acetanilide in three test tubes, each containing: water, 95% ethanol and hexane. The final weight produced by the pure acetanilide is 1.1g contrary to the weight of the crude of the acetanilide which is 0.5g. Quantitative analysis showed that the pure acetanilide produced 37.04% percentage yield. Introduction Recrystallization is a process of purifying organic compounds obtained from nature that contain soluble, insoluble and colored impurities. This is based on the premise that solubility increases on the increase of temperature while solubility decreases on the decrease of temperature. This is the process behind the formation of crystals. Recrystallization can be broken down into several steps. A suitable solvent is chosen followed by the compound being dissolved in a minimum solvent. Insoluble impurities are removed and crystallization follows upon cooling. The crystals are collected and dried. Choosing the best recrystallizing solvent would lead to the solubility of the impure substances in the compound. The boiling point of the recrystallizing solvent should be lower than the compound to be recrystallized. There are several criteria in determining the best recrystallizing solvent. The compound being purified must be insoluble in the solvent at room temperature. It should be insoluble in the solvent at high temperature. Upon low temperature, it should be soluble. Acetanilide can be obtained by acetylation of aniline undergone by nitration at low temperature. For acetylation of anilines, acetic anhydride is commonly used. Also called acetic acid anilide, acetanilide is an odorless, white crystalline powder which is soluble in hot water, alcohol, ether, chloroform, acetone, glycerol and benzene. It has a melting point of 114 à °C and boiling point of 314à °C. It is a combustible solid. When digested, it is moderately toxic. Exposure to body tissues would lead to irritation. For the production of rubber accelerators, dyes and camphor, acetanilide is used as an intermediate. It also used in penicillin synthesis and other pharmaceuticals like painkillers and intermediates. It is incompatible with strong alkalis and oxidizers but remains stable under normal conditions. Also, it is an amide. This experiment aims to purify crude acetanilide water, the best recrystallizing solvent, which is determined by the solubility of the solid compound, to produce pure acetanilide and to calculate the percentage yield of the weight of the pure acetanilide. Also, it aims to prove the process of recrystallization in purifying compounds. Materials and Methods The materials used were test tubes, Erlenmeyer flask, Bunsen burner, tripod, wire gauze, beaker, filter paper, aniline compound, hexane compound, acetic anhydride and methanol. The experiment began on the choosing of the recrystallizing solvent. Three test tubes that individually contained 1mL water, 95% ethanol and hexane were added a corn grain amount of pure acetanilide. Water was the chosenà recrystallizing solvent. In an Erlenmeyer flask, 2mL of aniline and 20mL of distilled water were mixed to be followed by the slow addition of 3mL acetic anhydride. This produced the crude acetanilide. The crude acetanilide was weighed. 20mL of recrystallizing solvent was added to the crude acetanilide. The solution was heated in the water bath until the solid dissolves. Activated charcoal is added to produce a colorless solution. While still hot, the solution was filtered through the filter paper. The crystals produced are collected, washed with distilled water and dried between filter papers. The resulting pure acetanilide is weighed Results and Discussion Choosing the recrystallizing solvent 3 test tubes containing 1mL water, 95% ethanol and hexane were subjected to different temperatures for 1-5 minutes in order to test the solubility of the pure acetanilide. In room temperature, water and hexane were insoluble; whereas, 95% ethanol was soluble. In high temperature or during heating, water and 95% ethanol are soluble while hexane was insoluble. In low temperature of upon cooling, water and 95% ethanol are both insoluble while hexane remained insoluble. Table 1 shows the result of the solubility of pure acetanilide in different temperatures provided. Table 1: Summary of the Solubility of Pure Acetanilide in Different Solvents of Varying Temperatures Solvent| At room temperature| During heating| Upon cooling| Water| Insoluble| Soluble | Insoluble| 95% ethanol| Soluble| Soluble| Soluble| Hexane| Inoluble| Insoluble| Insoluble| In order to attain the best recrystallizing solvent, this table explains that the compound should be very soluble in high temperatures and insoluble inà room temperature. The difference in hot and cold temperatures is essential for the process of recrystallization. It would not dissolve if at high temperatures the compound in the chosen solvent is insoluble. It would not crystallize in pure form if the compound in the solvent is soluble. The desired compound may be lost during recrystallization that is why the solvent should not react with the compound being purified. Unwanted impurities should be either very soluble in room temperature of insoluble in hot temperature. After the solution cools, the desired compound crystallizes and the remaining impurities will remain dissolved. After the compound has crystallized, the solvent should be volatile enough to be removed from the solvent after the compound. Easy and rapid drying of the solid compound after it has been isolated follows. Table 2 shows the weight of the crude acetanilide and the pure acetanilide. Table 2: Summary of the Weight of Crude and Pure Acetanilide Acetanilide| Weight (g)| Crude| 6.5| Pure| 1.2| Crude acetanilide was formed from the synthesis of acetanilide. Pure acetanilide was collected after recrystallizing the crude acetanilide. Quantitative Analysis of Acetanilide thru Determination of Percentage Yield The percentage recovery of pure acetanilide was computed using the formula: %Yield=Actual YieldTheoretical Yield x 100 Substituting the values: %Yield=1.1g2.97gx 100 Therefore, the percentage yield of pure acetanilide is 37.04%. Percentage yield is used in cases where chemical transformation occurs. In calculating the percentage yield, the following is needed: 1. The molar ratio of product to starting material 2. The molecular weights of product and starting material 3. Limiting Reagent Determination of Theoretical Yield 2mL Aniline (C6H5NH2) x 1.0271 mole x 1 mole93.13g x 102.09 g1 mole = 2.24g 3mL Acetic Anhydride (C4H6O3) x 1.0821 mole x 1 mole102.09g x 93.13g1 mole = 2.97g The limiting reagent is Aniline since 2.97g was needed to make 3 milliliters of Acetic Anhydride.
