Vedclass · Answer

(C) Sodium carbonate $(Na_2CO_3)$ is a salt formed from the neutralization of a strong base,sodium hydroxide $(NaOH)$,and a weak acid,carbonic acid $(H_2CO_3)$.When dissolved in water,it undergoes hydrolysis:$Na_2CO_3 + 2H_2O ⇌ 2NaOH + H_2CO_3$.Since $NaOH$ is a strong base and $H_2CO_3$ is a weak acid,the resulting solution contains an excess of $OH^-$ ions,making the solution alkaline (basic).

An aqueous solution of sodium carbonate is alkaline because sodium carbonate is a salt of
