Answer 1

Vinegar contains acetic acid.

Explanation:

Vinegar contains acetic acid (CH₃COOH), formed by the fermentation of ethanol by Acetobacter bacteria in the presence of oxygen. This acid gives vinegar its sour taste and strong smell. The concentration of acetic acid in household vinegar ranges from 4% to 8%, while specialty vinegars may have higher amounts. Depending on the source material, vinegar may also contain small amounts of vitamins, minerals, and organic acids.
