Chemistry - Ionic Equilibrium Question with Solution | TestHub

${\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4$ is a salt of strong acid and weak base, on hydrolysis it ill produce ${\mathrm{H}}^{+}$ion. This will increase the acidity of soil. $\begin{array}{rl}& {\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4⟶2{\mathrm{NH}}_4^{+}+{\mathrm{SO}}_4^{2-}\\ & {\mathrm{NH}}_4^{+}+{\mathrm{H}}_2\mathrm{O}\rightleftharpoons {\mathrm{NH}}_4\mathrm{OH}+{\mathrm{H}}^{+}\end{array}$ Hence, (D) is correct answer.
