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

Find out $K_a$ for the acid when the degree of hydrolysis of $0.1 \ M \ CH_3COONa$ is $1 \ \%$.

When $C_6H_5NH_3^+ Cl^-$ salt is dissolved in water,it undergoes hydrolysis. Find the equilibrium constant of the hydrolysis reaction if the ionization constant of the weak base is $10^{-4}$.
