Solution

A) Normal Slat is formed by the complete replacement of the acidic by a basic radical in a reaction.
Ex.- $N a C l, K N O_{3}, K C l,$ etc

B)An acidic salt is a salt which is prepared by from a strong acid and a weak base. An example of such salt is $N H_{4} C l$

$H C l + N H_{4} O H ⟶ N H_{4} C l + H_{2} O$

Ammonium hydroxide is a weak base, hydrochloric acid is a strong acid.

C) Mixed salt contains more than one acidic or basic radical.
Ex. - $C u N a P O_{4}, C a (O C l) C l,$ etc.
