Vedclass · Answer

(C) For a salt derived from a weak acid $(HA)$ and a weak base $(BOH)$,the hydrolysis reaction is: $B^+ + A^- + H_2O ightleftharpoons BOH + HA$. The equilibrium constant for this reaction is the hydrolysis constant $(K_h)$. It is related to the ionic product of water $(K_w)$,the dissociation constant of the acid $(K_a)$,and the dissociation constant of the base $(K_b)$ by the expression: $K_h = \frac{K_w}{K_a 	imes K_b}$.

The hydrolysis constant $(K_h)$ for a salt of a weak acid and a weak base is given by:
