(p)$\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{N}\mathrm{a}\rightleftharpoons \underset{\text{Weak acid}}{\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}{\mathrm{O}}^{-}}+\underset{\text{Strong base}}{\mathrm{N}{\mathrm{a}}^{+}}$(Basic)

(q)$\mathrm{N}{\mathrm{H}}_4\mathrm{C}\mathrm{l}\rightleftharpoons \underset{\text{Weak acid}}{\mathrm{N}{\mathrm{H}}_4^{+}}+\underset{\text{Strong acid}}{\mathrm{C}{\mathrm{l}}^{-}}$(Acidic)

(r)$\mathrm{N}\mathrm{a}\mathrm{N}{\mathrm{O}}_3\rightleftharpoons \underset{\text{Strong base}}{\mathrm{N}{\mathrm{a}}^{+}}+\underset{\text{Strong acid}}{\mathrm{N}{\mathrm{O}}_3^{-}}$(Neutral)

(s)$\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{N}{\mathrm{H}}_4\rightleftharpoons \underset{\text{Weak acid}}{\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}{\mathrm{O}}^{-}}+\underset{\text{Weak base}}{\mathrm{N}{\mathrm{H}}_4^{+}}$(Almost neutral)

May be slightly acidic or basic depending upon$\mathrm{p}{\mathrm{K}}_{\mathrm{a}}$and$\mathrm{p}{\mathrm{K}}_{\mathrm{b}}$values of acid and base.
