The conjugate base of benzoic acid, C6H5C(=O)OH, is benzoate, C6H5C(=O)O.

Explanation:

The conjugate base of any any acid is simply the parent acid, HA, less a proton, H+. Mass and charge are conserved. On the other hand, the conjugate acid of any base, A, is simply HA, that is the parent base plus a proton, H+.

Given this treatment, what is the conjugate base of hydroxide anion, HO?
