Acetic acid / ə ˈ s iː t ɪ k /, systematically named ethanoic acid / ˌ ɛ θ ə ˈ n oʊ ɪ k /, is an acidic, colourless liquid and organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H, C 2 H 4 O 2, or HC 2 H 3 O 2).
An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C 2 H 3 O − 2.
Vinegar typically contains from 5% to 18% acetic acid by volume. [1] Usually, the acetic acid is produced by a double fermentation, converting simple sugars to ethanol using yeast and ethanol to acetic acid using acetic acid bacteria. [2] Many types of vinegar are made, depending on source materials.

Acetoacetic acid (IUPAC name: 3-Oxobutanoic acid, also known as Acetonecarboxylic acid or Diacetic acid) is the organic compound with the formula CH 3 COCH 2 COOH. It is the simplest beta- keto acid , and like other members of this class, it is unstable.
If acetic acid, a weak acid with the formula CH 3 COOH, was made into a buffer solution, it would need to be combined with its conjugate base CH 3 COO − in the form of a salt. The resulting mixture is called an acetate buffer, consisting of aqueous CH 3 COOH and aqueous CH 3 COONa. Acetic acid, along with many other weak acids, serve as ...
