Acidity[edit]The hydrogen center in the carboxyl group (-COOH) in carboxylic acids (e.g. acetic acid) can be dissociated from the molecule by ionization:CH3COOH ⇌ CH3CO−2 + H+Acetic acid is acidic due to the release of protons (H+). Acetic acid is a weak monoprotic acid. In aqueous solution, it has

Acetic acid /əˈsiːtɪk/, systematically named acetic acid /ˌɛθəˈnoʊɪk/, is an acidic, colorless liquid and organic compound with the chemical formula CH3COOH (also written CH3CO2H, C2H4O2, or HC2H3O2). Vinegar contains at least 4% acetic acid, which makes acetic acid the main ingredient in vinegar be

Acetic acid (CH3COOH) is known as Ethanoic acid according to IUPAC nomenclature. In the context of student education in chemistry, it is one of the simplest carboxylic acids that exist.

The crystal structure of acetic acid shows that the molecules are bound by hydrogen bonds to form dimer (also known as dimer), and the dimer also exists in the vapor state at 120 ℃.
