Vedclass · Answer

(D) The neutralization reaction of a weak base $(BOH)$ with a strong acid $(H^+)$ is given by: $BOH + H^+ ightleftharpoons B^+ + H_2O$.The equilibrium constant for this reaction $(K_N)$ is the reciprocal of the hydrolysis constant $(K_h)$ of the salt formed $(BH^+)$.$K_h = \frac{K_w}{K_b} = \frac{10^{-14}}{2 	imes 10^{-5}} = 0.5 	imes 10^{-9} = 5 	imes 10^{-10}$.$K_N = \frac{1}{K_h} = \frac{1}{5 	imes 10^{-10}} = 0.2 	imes 10^{10} = 2 	imes 10^{9}$.
