what is cationic hydrolysis and anionic hydrolysis?
Salt hydrolysis: It is defined as a reaction in which cation or anion or both of a salt react with water to produce acidity or alkalinity.
The reaction of an anion or cation with water accompanied by cleavage of O-H bond is called hydrolysis.
- In anionic hydrolysis, the solution becomes slightly basic (p H >7).
- In cationic hydrolysis, the solution becomes slightly acidic (p H <7).
- Salts of weak acids and strong bases undergo anionic hydrolysis and yield basic solution.
- Salts of weak bases and strong acids undergo cationic hydrolysis and yield slightly acidic solution.
