Transition metals can be complexed by acetate. A commonly encountered acetate in the home is sodium acetate, a white solid that can be prepared by combining vinegar and sodium bicarbonate ("bicarbonate of soda"):ĬH 3COOH + NaHCO 3 → CH 3COO −Na + + H 2O + CO 2 Many acetate salts are ionic, indicated by their tendency to dissolve well in water. Above a pH of 5.5, acetic acid converts to acetate: CH 3COOH ⇌ CH 3COO − + H + The acetate anion, −,(or −) is one of the carboxylate family. eɪ t/), the common acetate remains the preferred IUPAC name. Care should also be taken to avoid confusion with peracetic acid when using the OAc abbreviation for clarity and to avoid errors when translated, HOAc should be avoided in literature mentioning both compounds.Īlthough its systematic name is ethanoate ( / ɪ ˈ θ æ n oʊ. For example, the formula for sodium acetate might be abbreviated as "NaOAc", rather than "NaC 2H 3O 2".

It is not to be confused with the symbol of actinium, the first element of the actinide series context guides disambiguation. Thus, HOAc is the symbol for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate (as Ac is common symbol for acetyl group CH 3CO ).The pseudoelement symbol "Ac" is also sometimes encountered in chemical formulas as indicating the entire acetate ion ( CHĢ). Chemists often represent acetate as OAc − or, less commonly, AcO −. When part of a salt, the formula of the acetate ion is written as CH In nature, acetate is the most common building block for biosynthesis. Most of the approximately 5 million tonnes of acetic acid produced annually in industry are used in the production of acetates, which usually take the form of polymers. The simplest of these is hydrogen acetate (called acetic acid) with corresponding salts, esters, and the polyatomic anion CH The neutral molecules formed by the combination of the acetate ion and a positive ion (called a cation) are also commonly called "acetates" (hence, acetate of lead, acetate of aluminium, etc.).
"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 CĢ.
alkaline, earthy, metallic, nonmetallic or radical base). An acetate is a salt formed by the combination of acetic acid with a base (e.g.
