Verified Solution

Answer & Solution

Correct Answer

(C) \(\mathrm{CO}_{3}^{2-}\) and water

Step-by-step Solution

Detailed explanation

\(\mathrm{Na}_{2} \mathrm{CO}_{3}+2 \mathrm{H}_{2} \mathrm{O} \rightleftharpoons 2 \mathrm{NaOH}+\mathrm{H}_{2} \mathrm{CO}_{3} \)
\( \text { or } 2 \mathrm{Na}^{+}+\mathrm{CO}_{3}^{2-}+2 \mathrm{H}_{2} \mathrm{O} \)
\( \rightleftharpoons 2 \mathrm{Na}^{+}+2 \mathrm{OH}^{-}+\mathrm{H}_{2} \mathrm{CO}_{3} \)
\( \text { or } \mathrm{CO}_{3}^{2-}+2 \mathrm{H}_{2} \mathrm{O} \rightleftharpoons 2 \mathrm{OH}^{-}+\mathrm{H}_{2} \mathrm{CO}_{3}\)
It is anionic hydrolysis.
