Benzoic acid, as its name implies, is an acid. Sodium benzoate is a salt of the conjugate base, the OBz- or benzoate ion. Whenever sodium benzoate dissolves in water, it dissociates into its ions. The benzoate ion then acts as a base toward water, picking up a proton to form the conjugate acid and a hydroxide ion.

Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. Commercially sold borax is partially dehydrated.
