Vedclass · Answer

(D) The degree of hydrolysis $(h)$ for a salt of a weak acid and a weak base is given by the formula: $h = \sqrt{K_h} = \sqrt{\frac{K_w}{K_a 	imes K_b}}$.Since $K_w$,$K_a$,and $K_b$ are constants at a given temperature,the degree of hydrolysis $(h)$ is independent of the concentration of the salt solution.Therefore,the degree of hydrolysis for all the given concentrations of $NH_4CN$ will be the same.
