Given below are two statements : Statement (I) : Aqueous solution...

Aqueous solution of $( {NH}_{4}{)}_{2}{CO}_{3}$ is Basic.

$pH$ of salt of weak acid and weak base depends on ${K}_{a}$ and ${K}_{b}$ value of acid and the base forming it.

Solution is basic if

${K}_{b}$(weak base) >${K}_{a}$(weak acid).

${K}_{a}$(${HCO}_{3}^{-}$)=$4 . 3 \times {10}^{- 13}$

${K}_{b} ( {NH}_{4}OH )=1 . 8 \times {10}^{- 5}$

${K}_{b}$ (Ammonium hydroxide) >${{K}_{a}}_{}$(Hydrogen carbonate)

∴ Hence, solution of Ammonium carbonate is basic in nature.

Hence Both Statement I and Statement II are correct.
