pH for the solution of salt undergoing anionic hydrolysis (say ${\mathrm{CH}}_3\mathrm{COONa}$) is given by:

pH for the solution of salt undergoing anionic hydrolysis,

$\mathrm{pH}=\frac{1}{2}\left[p{K}_w+p{K}_a+\log C\right]$

Here,

${\mathrm{K}}_{\mathrm{a}}=$Ionic product

 ${\mathrm{K}}_{\mathrm{w}}={10}^{-14}$
