    formula of a carboxylate ion Salts of carboxylic acids are named following the usual cation -then- anion conventions used for ionic compounds in both IUPAC and common nomenclature systems. The name of the carboxylate anion ( R−C(=O)O − ) is derived from that of the parent acid by replacing the "–oic acid" ending with "–oate" or ...
