Classify salts and explain each of them with examples.
Salts are classified into four types namely: normal salts, acid salts, basic salts and double salts.
1. Normal Salts
A normal salt is obtained by complete neutralization of an acid with a base.
NaOH+HCl→NaCl+H2O
2. Acid Salts
Acid salts are derived from the partial replacement of hydrogen ions of an acid by a metal. When a calculated amount of a base is added to a polybasic acid, acid salt is obtained as follows:
NaOH+H2SO4→NaHSO4+H2O
3. Basic Salts
Basic salts are formed by the partial replacement of hydroxide ions of a diacidic or triacidic base with an acid radical.
Pb(OH)2 + HCl→Pb(OH)Cl + H2O
(Diacidic base) Basic salt
A basic salt may further react with an acid to give a normal salt.
4. Double Salts
Double salts are formed by the combination of the saturated solution of two simple salts in equimolar ratio followed by crystallization. E.g. potash alum.
