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

The causes of acid rain are because of the emissions of sulphur dioxide and nitrogen oxides in the atmosphere. This is a result of pollution; sulphur dioxide primarily the result of industrialisation and coal fired power stations‚ and nitrogen oxides produced mainly due to car exhaust fumes. These either form wet or dry deposition‚ and the effects we can see today. It could be argued that once that the human race has used up all of the planets coal reserves‚ the problem of acid rain would disappear

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

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‚
