    Buffers - University of Texas at Austin

    Buffers. A buffer is a solution that contains substantial amounts of a compound in both its protonated and deprotonated forms. As such, it is "resistant" to pH change upon the addition of strong acid or strong base. This is because the protonated form can neutralize any strong base and the deprotonated form can neutralize any strong acid.

    Sodium benzoate is a salt of a weak acid (benzoic acid). In water, sodium benzoate hydrolyses to form a strong base (sodium hydroxide) and benzoinc acid. This is an equilibrium reaction.

    Is Sodium Benzoate an acid or a base? | AnswersDrive

    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 …
