Question

Define an acidic salt, a normal salt and a mixed salt. Give two examples in each case of: 

(a) a normal salt, 

(b) an acid salt, 

(c) a mixed salt.

Answer 1

Acidic salt: Acid salts are formed by the partial replacement of the ionizable hydrogen atoms of a polybasic acid by a metal or an ammonium ion.

Normal salt: Normal salts are the salts formed by the complete replacement of the ionizable hydrogen atoms of an acid by a metallic or an ammonium ion.

Mixed salt: Mixed salts are those salts that contain more than one basic or acid radical.

Examples:

(a) A Normal salt : Na₂SO₄ , NaCl

(b) An acid salt : NaHSO₄ , Na2HPO₄

(c) A mixed salt : NaKCO_{3 ,} CaOCl₂
