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.
Vinegar consists of acetic acid (CH3
COOH), 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.
