Q. HA is a weak acid and BOH is a weak base. For which of the following salts the extent of hydrolysis is independent on the concentration of the salt in its aqueous solution

Solution:

The extent of the hydrolysis (h) of the salt made by weak acid and weak base is independent on the concentration of the salt

$h=\frac{\sqrt{K_{h}}}{\sqrt{K_{h} + 1}}$

$K_{h}=hydrolytic \, constant=\frac{K_{w}}{K_{a} K_{b}}$
