The Synthesis of Organic Aspirin ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin‚ and to become familiar with achieving successful yields. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is used separate the impurities from the crude aspirin. To get purified aspirin‚ the precipitate was heated until all

Analysis of Aspirin Problem: Was aspirin (acetylsalicylic acid) successfully synthesized? Are there impurities or by-products present in the synthesized aspirin? How pure is the synthesized aspirin? Introduction: In the last experiment‚ aspirin was synthesized followed by characterization of the product using several different techniques. Melting point was a test that provided information about the identity and purity of the aspirin product. The iron(III)chloride test was used to detect the

A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They are the most common type of organic acid. Among

INTRODUCTION The Gram Negative lab had two parts; the aim of the first part is to determine the concentration of gram negative bacteria in a water sample collected from a creek near Providence Road‚ Strickling. Gram negative bacteria have a cytoplasmic membrane‚ a thin peptidoglycan layer‚ and an additional outer membrane composed of phospholipids and lipopolysaccharides. Because gram negative bacteria have a relatively thin cell wall when compared to gram positive organisms‚ they are consequently

What is acetylsalicylic acid? Acetylsalicylic acid (ASA)‚ or more commonly known as aspirin‚ is a medication that can be used for pain‚ fevers‚ and inflammation. It can be used for long periods of time‚ in small amounts‚ to prevent heart attacks‚ strokes and the formation of blood clots. A heart attack victim can be given a low dose right after the ordeal to reduce the risk of another one. Side effects of this drug is ulcers‚ internal bleeding (stomach) and ringing in the ears. These mainly happen

ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

Judson Cotterman III 4/6/2012 Section 185-35L Assignment #3 Gram-positive Pathogenic Cocci Discussion My original hypothesis for the individually collected throat culture on Blood Agar Plates‚ that it would show a mixture of alpha‚ beta‚ and gamma hemolysis‚ was based on the results of the class control samples of S. pneumonia‚ S. aureas and S. epidermis. In these controls S. pneumonia shows alpha and beta hemolysis while S. aureas and S. epidermis showed beta and gamma hemolysis respectively.

difference was evaluated. Chemical reactions in a calorimeter were used to determine the amount of heat produced by a reaction. Reactions that absorb heat were noted as endothermic‚ and reactions that release heat were noted as exothermic. These principals were based off of Hess’s Law. The goal of the experiment was to monitor chemical reactions using a calorimeter to monitor changes in temperature. The changes in temperature were to be used to find the amount of heat released or absorbed. EXPERIMENTAL
