Answer:
(c) Ammonium acetate is salt of
weak acid and weak base, its pH after hydrolysis can be calculated as.
\[pH=\frac{1}{2}[p{{K}_{w}}+p{{K}_{a}}-p{{K}_{b}}]\]
\[=\frac{1}{2}[14+p{{K}_{a}}-p{{K}_{b}}]\]
\[\text{=
7}\,\,\,\,\,\text{since(p}{{\text{K}}_{\text{a}}}\text{= p}{{\text{K}}_{\text{b}}}\text{)}\]
