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

Sarah Khan Bivins-5th April 20th‚ 2013 Protein Synthesis Every day‚ you take in an abundance of different biomolecules; one of them being proteins. Have you ever wondered how proteins are made? They don’t just grow from a tree or fall from the sky‚ they are made through a process called protein synthesis. Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

The War on Drugs and The Legalization of Marijuana Marijuana is the most commonly used illegal drug in the world.

The flowers on

Synthesis of Aspirin Name: Xuanyi Li Teaching assistant: Deirdre Zwilling November 15‚ 2009 Purpose: To synthesize aspirin‚ a common analgesic drug‚ via nucleophilic acid-catalyzed substitution reaction of salicyclic acid with acetic anhydride. The whole reaction is catalyzed by phosphoric acid. (The experiment involved three parts: The synthesis of aspirin‚ the isolation and purification of aspirin‚ and the estimation of the purity of the final product.) [pic] Procedure[1]: A mixture

Should marijuana be legalized for personal use? This is a question that many have been asking as well as debating over for many years. Marijuana has been used for many medicinal purposes throughout medical history. However‚ many consider marijuana to be gateway drug that could lead to harder drug use.
