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

• A

  $\mathrm{pH}=1/2 \left[{\mathrm{pK}}_{\mathrm{w}} + {\mathrm{pK}}_{\mathrm{a}} + \log \mathrm{C}\right]$

• B

  $\mathrm{pH}=1/2 \left[{\mathrm{pK}}_{\mathrm{w}} + {\mathrm{pK}}_{\mathrm{a}} - \log \mathrm{C}\right]$

• C

  $\mathrm{pH}=1/2 \left[{\mathrm{pK}}_{\mathrm{w}} + {\mathrm{pK}}_{\mathrm{b}} - \log \mathrm{C}\right]$

• D

  None of these
