Acetates
An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic, or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula . The neutral molecules formed by the combination of the acetate ion and a ''positive'' ion (called a cation) are also commonly called "acetates" (hence, ''acetate of lead'', ''acetate of aluminium'', etc.). The simplest of these is hydrogen acetate (called acetic acid) with corresponding salts, esters, and the polyatomic anion , or . Most of the approximately 5 million tonnes of acetic acid produced annually in industry are used in the production of acetates, which usually take the form of polymers. In nature, acetate is the most common building block for biosynthesis. Nomenclature and common formula When part of a salt, the formula of the acetate ion is ...

Acetic Acid
Acetic acid , systematically named ethanoic acid , is an acidic, colourless liquid and organic compound with the chemical formula (also written as , , or ). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. Historically, vinegar was produced from the third century BC and was likely the first acid to be produced in large quantities. Acetic acid is the second simplest carboxylic acid (after formic acid). It is an important Reagent, chemical reagent and industrial chemical across various fields, used primarily in the production of cellulose acetate for photographic film, polyvinyl acetate for wood Adhesive, glue, and synthetic fibres and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is controlled by the E number, food additive code E260 as an acidity regulator and as a condiment. In biochemistry, the acetyl group, derived from acetic acid, is funda ...

Aluminium Acetate
Aluminium acetate or aluminium ethanoate (also "aluminum ~"), sometimes abbreviated AlAc in geochemistry, can refer to a number of different salts of aluminium with acetic acid. In the solid state, three salts exist under this name: basic aluminium monoacetate, (HO)2AlCH3CO2, basic aluminium diacetate, HOAl(CH3CO2)2, and neutral aluminium triacetate, Al(CH3CO2)3. In aqueous solution, aluminium triacetate hydrolyses to form a mixture of the other two, and all solutions of all three can be referred to as "aluminium acetate" as the species formed co-exist and inter-convert in chemical equilibrium. Stoichiometry Monoacetate Aluminium monoacetate, also known as dibasic aluminium acetate, forms from Al(OH)3 and dilute aqueous acetic acid. More concentrated acid leads to the di- and triacetate. Diacetate Aluminium diacetate, also known as basic aluminium acetate, is prepared from aqueous aluminium acetate solution resulting in a white powder. This basic salt forms from the h ...

Sodium Acetate
Sodium acetate, CH3COONa, also abbreviated Sodium, NaOxygen, OAcetyl, Ac, is the sodium Salt (chemistry), salt of acetic acid. This salt is colorless, deliquescent, and hygroscopy, hygroscopic. Applications Biotechnological Sodium acetate is used as the carbon source (biology) , carbon source for culturing Bacterial growth, bacteria. Sodium acetate can also be useful for increasing yields of DNA extraction, DNA isolation by ethanol precipitation. Industrial Sodium acetate is used in the textile industry to neutralize sulfuric acid waste streams and also as a photoresist while using aniline dyes. It is also a pickling (metal), pickling agent in chrome Tanning (leather), tanning and helps to impede vulcanization of chloroprene in synthetic rubber production. It is also used to reduce static electricity during production of disposable cotton pads. Concrete longevity Sodium acetate is used as a sealant to mitigate water damage to concrete. It is environm ...
