choosing a topic for a research paper. The first situation occurs when the instructor provides a list of topics from which the student may choose. These topics have been deemed worthy by the instructor; therefore‚ the student should be confident in the topic he chooses from the list. Many first-time researchers appreciate such an arrangement by the instructor because it eliminates the stress of having to decide upon a topic on their own. However‚ the student may also find the topics that have been

acidification of salicylic acid and acetic anhydride. The objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore‚ the other objectives were to enable students to conduct the synthesis of aspirin‚ reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is a 1:1 ratio between them. The purity of the synthesized aspirin was measured by determining

Jeana Greaves Chem3301-112 June 19‚ 2013 Synthesis of Aspirin from Methyl Salicylate Introduction The synthesis of Aspirin (Acetyl Salicyclic Acid) began with methyl salicylate and sodium hydroxide as the reagent. The polar oxygen accepts the electrons from now positively charged hydrogen. The positively charged sodium disassociates leaving the hydroxide ion with a negative Scheme 1 shows the mechanisms that were demonstrated during the synthesis of Aspirin. charge that attracts to the positively

Career Research It is rather unusual that I chose a dangerous field‚ which is being in the Navy‚ instead of being the stereotypical Asian doctor despite having a good family. My father has always told me these words‚ “ Whatever you choose‚ I will support you. Unless it’s drugs or anything like that‚ I will kick your ass. I rather see you fail trying to be successful than not try without experiencing failure”. Those words have pierced deep into my mind since I knew the harsh struggles my family

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

Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural
