Vedclass · Answer

(B) For a salt of a weak acid and a weak base,the degree of hydrolysis $(h)$ is given by the formula: $h = \sqrt{K_h} = \sqrt{\frac{K_w}{K_a 	imes K_b}}$.Since the expression for the degree of hydrolysis $(h)$ does not contain any concentration term,it is independent of the concentration of the salt solution.Therefore,if the degree of hydrolysis is $50 \ \%$ at $0.1 \ M$,it will remain $50 \ \%$ at $0.5 \ M$ as well.

The degree of hydrolysis of a salt of a weak acid and a weak base in its $0.1 \ M$ solution is found to be $50 \ \%$. If the molarity of the solution of the same salt is $0.5 \ M$,then the percentage degree of hydrolysis of the salt should be ......... $\%.$
