Acetate

From Biocrawler, the free encyclopedia.

Acetate, or ethanoate, is the anion of a salt or ester of acetic acid.

In Organic chemistry, the acetate ion has the formula CH₃CO₂^-, and is the conjugate base of acetic acid.

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

Historically (prior to the discovery and naming of actinium) the abbreviation Ac (or AC) was sometimes used in chemical formulas to indicate the acetate ion. For example, the formula for sodium acetate might be given as "NaAc", rather than the more modern "CH₃COONa" or "NaC₂H₃O₂".cs:Acetátfr:Acétate nl:Acetaat
