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.
Also question is, is sodium benzoate acidic?
The chemical is a preservative commonly found in foods most people consume daily, usually beverages such as sodas and juice drinks that are acidic. Sodium benzoate is produced by a reaction of benzoic acid with sodium hydroxide, which makes it disolve in water.

Additionally, what is the pH of sodium benzoate?
It is soluble in water where it converts to benzoic acid, its active form, at a low pH. Benzoic acid is very pH dependent. While it shows some activity up to pH 6 (about 1.55%), it is most active at pH 3 (94%). Info.
