Solution

The correct option is C $K_{w} / K_{a} K_{b}$
The hydrolysis constant of a weak base is $\frac{K_{w}}{K_{a} K_{b}}$ , the degree of hydrolysis is $\sqrt{\frac{K_{w}}{K_{a} K_{b}}}$ and the pH of the solution is given by $1 / 2 p K_{w} + 1 / 2 p K_{a} - 1 / 2 p K_{b} .$
an example of a weak acid and a weak base is $C H_{3} C O O N H_{4}$
