of Acetylsalicylic Acid Abstract Acetylsalicylic acid was prepared using salicylic acid and acetic anhydride. As a result‚ a white‚ powdery substance was formed (0.1931g‚ percent yield 91.30%) and was defined by melting point (124.5 – 134.5°C) and observation of color change with ferric chloride. Introduction Acetylsalicylic acid (aspirin) is one of the most popular analgesic drugs on the market today. It also acts as an antipyretic and anti-inflammatory drug. Salicylic acid itself was too acidic

Objectives 1. To separate a mixture of an acid and a neutral compound into its component by extraction. 2. To determine the melting point and the yield of the benzoic acid and the unknown sample. 3. To determine the unknown sample whether is is Trimethylmethanol or 1‚2‚4‚5-Tetrachlorobenzene. Introduction Extraction is a process of transferring a solute from one solvent to another. It is usually used to separate one or more components from a mixture. Diethyl ether‚ dichloromethane

INTRODUCTION Lactic Acid is an organic compound with the formula CH3CH (OH) COOH. Lactic is one of the types of fermentation which occur under anaerobic respiration to produce ATP without the use of oxygen. Anaerobic respiration takes place in certain prokaryotic organisms that have an Electron Transport Chain (ETC) but do not use oxygen as a final electron acceptor at the end of the chain (Campbell et all‚ 2015) different with the aerobic respiration which use oxygen to produce ATP and its final

DKFLSDFKLFKJ | Acid-Base Titration. | kfjhdkjhvdkfj | | April Jowers | 12/19/2012 | DKFJSDKJFHDSKJHF | Introduction In this lab we will use basic titrating skills and techniques in order to titrate HCl. We will also be practicing how to prepare the solution. Using the titration data‚ we can practice our stoichiometric skills and also become more familiar with using lab equipment. Titration is the process of measuring the exact volume of a solution of known concentration that is

Introduction: In this lab‚ we measured the acid-base strengths of seven separate organic compounds. The lab was painless to perform‚ it consisted of adding a small amount of one of the organic compounds to a well‚ and testing the pH via testing paper. The color of the paper was then analyzed to determine what the pH of the compound was. The structures were benzenesulfonic acid‚ benzoic acid‚ benzyl alcohol‚ benzylamine‚ p-cresol‚ and p-toluidine. My initial hypothesis about the acidity/basicity

How to Catch a Criminal‚ Crime Show Addition These days there are a number of crime shows that air on T.V. Some of the techniques for solving a crime are the same on these shows‚ but each has a feature that the others do not present in that show. These shows are considered fictional‚ but some are based on actual events or crimes that have happened. The writer loves to watch these types of shows and attempts to figure out “who did it.” Some people may feel these shows are too vivid or not

The more hydrogen ions in the acid more powerful the acid will be. Acid is in everyday things from eating and drinking to sleeping. Acid is in coffee‚ toothpaste‚ oranges‚ fruit‚
