Question

What are four types of salts?

Answer in Brief

Solution

Types of Salts

1. Normal Salts
A normal salt is obtained by the complete neutralization of an acid by a base.
NaOH + HCl ➝ NaCl + H2O

2. Acid Salts
It is 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.
NaOH + H2S02 ➝ NaHS04 + H20

3. Basic Salts
Basic salts are formed by the partial replacement of hydroxide ions of an acidic or triadic base with an acid radical.
Pb(OH)2 + HCl ➝ Pb(OH)Cl + H2O

4. Double Salts
Double salts are formed by the combination of the saturated solution of two simple salts in an equimolar ratio followed by crystallization. For example, Potash alum is a mixture of potassium sulfate and aluminum sulphate.
KAI(SO4)2·12H2O
