Vedclass · Answer

(C) Ammonium benzoate $(C_6H_5COONH_4)$ is a salt formed from a weak acid (benzoic acid,$K_a$) and a weak base (ammonium hydroxide,$K_b$).For a salt of a weak acid and a weak base,the degree of hydrolysis $(h)$ is independent of the concentration $(C)$ of the salt solution.The hydrolysis constant $(K_h)$ is given by $K_h = \frac{K_w}{K_a 	imes K_b}$.The degree of hydrolysis $(h)$ is given by the formula $h = \sqrt{K_h}$.Substituting the value of $K_h$,we get $h = \sqrt{\frac{K_w}{K_a 	imes K_b}}$.

Which formula represents the degree of hydrolysis $(h)$ for ammonium benzoate $(C_6H_5COONH_4)$?
