Lets churn chemistry-Acetates

Chemistry is a very interesting branch of science.Chemistry's branch is Organic Chemistry which is too a interesting subject.There are billions and trillions of organic compounds.Acetates being some of them.
                Acetates are very common compounds which we use everyday.The vinegar that we consume is Acetic acid.Now we are going to discuss about acetates.An acetate is a derivative of Acetic acid.
                This term includes salts and esters, as well as the anion found in solution. Most of the approximately 5 billion kilograms of acetic acid produced annually in industry are used in the production of acetates, which usually take the form of polymers.International Union of Pure and Applied Chemistry has sanctioned that acetates would be written ethanoates.Many acetate salts are ionic, indicated by their tendency to dissolve well in water. A commonly encountered acetate in the home is sodium acetate, a white solid that can be prepared by combining vinegar and sodium bicarbonate("bicarb").The acetate anion, [CH3COO], is one of the carboxylate family. It is the conjugate base of acetic acid. Above pH of 5.5, acetic acid converts to acetate.Commercially important acetate salts are aluminium acetate used in dyeing, ammonium acetate, a precursor to acetamide, and potassium acetate, used as a diuretic. All three salts are colourless and highly soluble in water.Acetate is a common anion in biology. It is mainly utilized by organisms in the form of acetyl coenzyme A.Acetates are very very common in day to day life and its uses are various.
