A neutral salt arises due to the neutralization reaction. Here, salts of strong acid and strong base combine to form such salts that show a neutral pH of 7.
An acid salt is formed when a strong acid combines with a weak base. It liberates hydrogen or hydronium ions, it exhibits some acidic properties. Hence it behaves like an acid and has a pH of less than 7.
A basic salt may also be formed by the partial replacement of the hydroxyl groups of a diacidic or triacidic base, by an acid radical.
Basic salts are stronger in their basic nature and show a pH greater than 7.
