Vedclass · Answer

(A) For a salt of a weak acid and a weak base,the degree of hydrolysis $(h)$ is independent of the concentration of the salt solution.The formula for the degree of hydrolysis is given by: $h = \sqrt{\frac{K_w}{K_a 	imes K_b}}$Given values: $K_w = 10^{-14}$,$K_a = 10^{-5}$,$K_b = 10^{-5}$.Substituting the values: $h = \sqrt{\frac{10^{-14}}{10^{-5} 	imes 10^{-5}}} = \sqrt{\frac{10^{-14}}{10^{-10}}} = \sqrt{10^{-4}} = 10^{-2}$.

Calculate the degree of hydrolysis of a salt formed from $0.1 \ N$ $NH_4OH$ and $0.1 \ N$ $HCN$. Given $K_a = 10^{-5}$ and $K_b = 10^{-5}$.
