Dear student,
The process of interaction between cations or anions of salts and water is known as hydrolysis of salts.
salts are divided into three parts on the basis of hydrolysis,:
Acid salts
basic salts
neutral salts
Salts of weak acid and strong base : CH3COONa
Salts of strong acid and strong base: NaCl
Salts of strong acid and weak base: NH4Cl
Salts of weak acid and weak base:CH3COONH4
