Chemistry - Ionic Equilibrium Question with Solution | TestHub

$\mathrm{N}{\mathrm{H}}_4\mathrm{C}\mathrm{l}$undergoes cationic hydrolysis hence$\mathrm{p}\mathrm{H}$is$<7$because the solution due to cationic hydrolysis in acids.
$\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{N}$undergoes anionic hydrolysis hence$\mathrm{p}\mathrm{H}$is$>7$.
$\mathrm{H}\mathrm{C}\mathrm{l}$is strong acid and$\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{l}$is neutral solution.
Hence the$\mathrm{p}\mathrm{H}$of given solutions will increases.
$\mathrm{H}\mathrm{C}\mathrm{l}<\mathrm{N}{\mathrm{H}}_4\mathrm{C}\mathrm{l}<\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{l}<\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{N}$
