When part of a salt, the formula of the acetate ion is written as CH 3CO 2, C 2H 3O 2, or CH 3COO . Chemists often represent acetate as OAc or, less commonly, AcO . 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 CH3CO ).The pseudoelement symbol "Ac" is also sometimes encountered in chemical formulas as indicating the entire acetate ion (CH 3CO 2).
