The correct answer is: $\mathrm{CO}_{3}^{2-}$ and water
$\begin{aligned} \mathrm{Na}_{2} \mathrm{CO}_{3}+2 \mathrm{H}_{2} \mathrm{O} & \rightleftharpoons 2 \mathrm{NaOH}+\mathrm{H}_{2} \mathrm{CO}_{3} \\ & \text { or } 2 \mathrm{Na}^{+}+\mathrm{CO}_{3}^{2-}+2 \mathrm{H}_{2} \mathrm{O} \\ & \rightleftharpoons 2 \mathrm{Na}^{+}+2 \mathrm{OH}^{-}+\mathrm{H}_{2} \mathrm{CO}_{3} \\ & \text { or } \mathrm{CO}_{3}^{2-}+2 \mathrm{H}_{2} \mathrm{O} \rightleftharpoons 2 \mathrm{OH}^{-}+\mathrm{H}_{2} \mathrm{CO}_{3} \end{aligned}$
