Question: What Is the Chemical Composition of Vinegar?
Vinegar is a liquid that is produced from the fermentation of ethanol into acetic acid. The fermentation is carried out by bacteria.
Answer: Vinegar consists of acetic acid (CH3COOH), water and trace amounts of other chemicals, which may include flavorings. The concentration of the acetic acid is variable. Distilled vinegar contains 5-8% acetic acid. Spirit of vinegar is a stronger form of vinegar that contains 5-20% acetic acid.

Flavorings may include sweeteners, such as sugar or fruit juices. Infusions of herbs, spices and other flavors may be added, too.
