Acetic Acid, also known as ethanoic acid, is a two-carbon carboxylic acid. Its formula is: CH3COOH. Acetic Acid is a colorless liquid that has a characteristic pungent odor, boils at 118°C, and is miscible with water in all proportions. It is one of the simplest organic carboxylic acid. However, it is a weak acid, in which it is only a partially dissociated acid in an aqueous solution.
Nevertheless, Acetic acid is the major acid in vinegar; as such, it is widely used as a food preservative and condiment. For industrial use concentrated acetic acid is prepared from the oxidation of acetaldehyde. Acetic acid is also a product in the destructive distillation of wood. These include cellulose acetate, used in making acetate rayon, nonflammable motion-picture film, lacquers, and plastics; various inorganic salts. For example: lead, potassium, and copper acetates; and amyl, butyl, ethyl, methyl, and propyl, acetates which are used as solvents, chiefly in certain quick-drying lacquers and cements.
It is an important chemical reagent and industrial chemical, used in the production of polyethylene terepthlate mainly used in soft drink bottles; cellulose acetate, mainly for photographic film; and polyvinyl acetate for wood glue, as well as synthetic fibers and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is used under the food addictive code E260 as an acidity regulator and as a condiment.

Health benefits of Acetic Acid

In India, Ayurvedic physicians prescribe apple cider vinegar in combination with the herb Gotu Kola to help in the revitalizing of the skin. Indians have been known to consume apple cider vinegar in combination with honey to improve digestion.
Also, it contributes greatly to the breaking down of food in the body and also prevents harmful bacteria from multiplying. Even respiratory infections can be kept at bay, sore throats improve, and nasal discharges decrease. Besides, vinegar helps prevent the accumulation of body fat. It turns on genes that produce proteins involved in breaking down fats, which in turn suppresses body fat accumulation.

Acetic Acid harmful


Concentrated acetic acid is corrosive and must, therefore, be handled with appropriate care, since it can cause skin burns, permanent eye damage, and irritation to the mucous membranes. These burns or blisters may not appear until hours after exposure.
