Chemistry - Ionic Equilibrium Question with Solution | TestHub

Consider the three solutions of 1 M concentration
$1.$Sodium acetate$\left(\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{N}\mathrm{a}\right)$
$2.$Acetic acid + Sodium acetate$(\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}+\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{N}\mathrm{a})$
$3.$Acetic acid$\left(\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}\right)$
The pH of these solutions will be lie in the following sequence
