Vedclass · Answer

(A) $Na_2CO_3$ is a salt of a strong base $(NaOH)$ and a weak acid $(H_2CO_3)$.When dissolved in water,it undergoes anionic hydrolysis.The carbonate ion $(CO_3^{2-})$ reacts with water to produce $OH^-$ ions:$CO_3^{2-} + H_2O \rightleftharpoons HCO_3^- + OH^-$.Due to the presence of $OH^-$ ions,the solution becomes basic in nature.Therefore,the $pH$ of the solution is greater than $7$.

The solution of $Na_2CO_3$ has $pH$:
