Acetic acid‚ a pungent smelling colourless liquid having sour taste‚ used very commonly in the chemistry laboratories. It got its name from Latin word Acetum‚ which means vinegar. Pure acetic acid is also called glacial acetic acid‚ because in winters it freezes easily as temperature goes below 16-17°C. Therefore it looks like as if a small glacier is there in the bottle‚ hence called glacial acetic acid. Laboratory and daily life uses of acetic acid are: (i) Acetic acid is used in household kitchens

Sulfuric Acid is one of the the important chemical compounds. A Great amount of sulfur is mined all around the world and is used to produce sulfuric acid. Sulfuric acids being produced Sulfuric acid may seem like something to find in a lab‚ perhaps under the label “corrosive‚” and in some kind of tube that isn’t affected by it. But‚ in reality‚ it’s quite common‚ and is used often in the industrial business‚ for many different objects. Because of this‚ many places can often be judged upon their

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

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
