Acetate

An acetate, or ethanoate, is either a salt or ester of ethanoic acid.

In chemistry, the abbreviation Ac refers to the acetyl group. The anion and the functional group may be written as ⁻OAc and AcO⁻, or OAc respectively. Examples include HOAc for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate.

Salt

The acetate anion, [CH₃COO]⁻, is a carboxylate and is the conjugate base of acetic acid. The acetate ion is formed by the deprotonation of acetic acid:

CH₃COOH ⇌ CH₃COO⁻ + H⁺

(more easily written as: C₂H₃O₂^-)

Ester

An acetate ester is an ester of acetic acid, with the general formula CH₃COOR, where R is an organyl group.

Acetate can also refer to cellulose acetate, especially fibres or other derived products such as the acetate disc used in audio record production. Cellulose acetate can be found in many household products.
