CHEMISTRY 101.1 Intermediate Chemistry Laboratory I Institute of Chemistry University of the Philippines‚ Diliman I. Synthesis of Salicylic Acid Purpose: Part I of the experiment illustrates the base hydrolysis of an ester‚ methyl salicylate‚ to form salicylic acid through nucleophilic acyl substitution. Procedure: Dissolve 12 g NaOH in 70 mL water in a 150 mL round bottom flask. Add 5.0 mL methyl salicylate and reflux the reaction mixture at its boiling point for 15 minutes using a stirrer

In modern day‚ man does not truly think about how much the earth means to life. On the contrary‚ humans aspire to cease Mother Nature’s beauty with the replacement of modern day cities made up of synthetic nature. Since the dawn of the twentieth century‚ a major theme in the American Arts has been the protest against man’s destruction of the natural world. With this in mind‚ as very well argued in Chief Seattle’s article “Respect”‚ humans fail to be conscious of the physical and sentimental value

aqueous solution of formaldehyde is called formalin. The commercially available formalin has 10 to 12% methanol with a few impurities like aluminum and copper. Almost 21 million tonnes of formaldehyde is produced annually all around the world. Synthesis of Formaldehyde Formaldehyde is produced by catalytic oxidation of methanol. A mixture of molybdenum and iron or silver is used as a catalyst in such a reaction. But a more commonly used process is FORMAX. In this process‚ methanol and oxygen

Explanatory Synthesis A countless number of children in the United States were taught to believe that you could accomplish anything if you worked hard. This American dream has now become an American nightmare. According to the information in the Hart Research Associations titled “Raising the Bar‚” “ How the Rich are getting Richer and Poor are getting Poorer‚” and the Workforce Commission powerpoint‚ Americans are faced with many obstacles to learn how to survive in the economy.

FWIS 104 Christian and Muslim Religious Tolerance It is ironic that while they are based on similar scriptures‚ and therefore similar ideologies‚ Christianity and Islam have had divergent attitudes towards the acceptance of religious minorities. By its nature‚ the Christian faith antagonizes other religions‚ including Judaism and Islam‚ because‚ according to Christian scripture‚ a lack of belief in the divinity of Jesus Christ results in damnation. The Muslim faith‚ however‚ has a much more tolerant

The two passages dealt with religious tolerance‚ each from a different perspective. The first passage‚ John Locke’s "A Letter Concerning Toleration" from 1689‚ was written from the viewpoint of a man under a king’s rule in England. The second passage‚ "The Blind Men and the Elephant‚" is a Buddhist parable. Locke’s reasoning for religious tolerance is all over the place. He first explains that no man has any right to enforce his beliefs on another man‚ stating that faith comes from within one’s

Experiment 2 and 3: Synthesis of Aspirin and Determination of Melting Point A. Abstract Aspirin is the common name for the compound acetylsalicylic acid‚ widely used as a fever reducer and as a pain killer. The first part of the experiment aims to synthesize aspirin from the reaction of salicylic acid with acetic anhydride with the aid of phosphoric acid as a catalyst. The second part of the experiment aims to assess the purity of aspirin through the determination of its melting point and
