$Na_2CO_3$

Vedclass · Answer

(B) salt formed from a strong base and a weak acid undergoes anionic hydrolysis to form a basic solution. $Na_2CO_3$ is a salt of a strong base $(NaOH)$ and a weak acid $(H_2CO_3)$. When dissolved in water,the carbonate ion $(CO_3^{2-})$ reacts with water: $CO_3^{2-} + H_2O \rightleftharpoons HCO_3^- + OH^-$. The production of $OH^-$ ions makes the solution basic. $NH_4NO_3$ and $NH_4Cl$ are salts of a weak base and a strong acid,forming acidic solutions. $Na_2SO_4$ is a salt of a strong base and a strong acid,forming a neutral solution.

Which among the following salts forms a basic solution in water?
