vinegar contains what kind of acid
Vinegar is a liquid consisting mainly of acetic acid (CH 3 COOH) and water. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria.Vinegar is now mainly used as a cooking ingredient.Historically, as the most easily available mild acid, it had a great variety of industrial, medical and domestic uses, some of which (such as its use as a general household cleanser) are still promoted today.he term distilled vinegar is something of a misnomer, because it is not produced by distillation but by fermentation of distilled alcohol. The fermentate is diluted to produce a colorless solution of 5% to 8% acetic acid in water, with a pH of about 2.4.
