Vedclass · Answer

(C) The hydrolysis constant $K_h$ is related to the dissociation constants of the acid $(K_a)$ and base $(K_b)$ and the ionic product of water $(K_w)$.For a salt of a weak acid and a strong base (e.g.,$CH_3COONa$),the hydrolysis constant is given by $K_h = K_w / K_a$.For a salt of a strong acid and a weak base (e.g.,$NH_4Cl$ or $FeCl_3$),the formula is $K_h = K_w / K_b$.For a salt of a weak acid and a weak base (e.g.,$CH_3COONH_4$),the formula is $K_h = K_w / (K_a 	imes K_b)$.Thus,$K_h = K_w / K_a$ applies to $CH_3COONa$.

The formula $K_h = K_w / K_a$ is applicable to which of the following salts?
