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 to produce $OH^{-}$ ions,making the solution basic.The hydrolysis reaction is: $CO_3^{2-} + H_2O \rightleftharpoons HCO_3^{-} + OH^{-}$.Since the solution contains excess $OH^{-}$ ions,it is basic in nature.Therefore,the $pH$ of the solution will be greater than $7$,falling in the range of $7-14$.

$A$ few grams of sodium carbonate $(Na_2CO_3)$ is added to $1 \ L$ of water. What is the $pH$ or $pH$ range of the resultant solution?
