Assertion: When aqueous, solution of CH₃COOAg is diluted, then its degree of hydrolysis increases. Reason:  Silver  acetate  is  the  salt  of  weak  acid  and weak base; its degree of hydrolysis does not depend on the concentration.

Since, the degree of hydrolysis does not depend on the concentration  of  the  salt,  dilution  of  the  solution  will not affect the degree of hydrolysis. So, the asserti
