(a) Whenever a strong acid reacts with a weak base, the salt formed is termed as an acidic salt. The examples of acidic salts include Ammonium Chloride- NH₄Cl [Salt formed when HCl reacts with NH₄OH], Aluminium Sulphate -Al ₂(SO₄)₃ [Salt formed when H₂SO₄ reacts with Al (OH) ₃].

(b) Whenever a strong base reacts with a weak acid, the salt formed is termed as a basic salt. The examples of basic salt is as follows: Sodium Carbonate- Na₂CO₃ [salt formed when NaOH reacts with H₂CO₃] etc
