Question

Complete the following reaction:

${\mathrm{Na}}_2{\mathrm{CO}}_3+{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O}\stackrel{}{\to }----$

Answer 1

The reaction of sodium carbonate with carbon dioxide and water:

• When sodium carbonate$\left({\mathrm{Na}}_2{\mathrm{CO}}_3\right)$ reacts with carbon dioxide $\left({\mathrm{CO}}_2\right)$ and water$\left({\mathrm{H}}_2\mathrm{O}\right)$, resulting in the formation of sodium bicarbonate$\left({\mathrm{NaHCO}}_3\right)$.
• $\underset{\mathrm{sodium}\mathrm{carbonate}}{{\mathrm{Na}}_2{\mathrm{CO}}_3\left(\mathrm{s}\right)}+\underset{\mathrm{carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)}\underset{\mathrm{sodium}\mathrm{bicarbonate}}{\stackrel{}{\to 2}{\mathrm{NaHCO}}_3(\mathrm{s}})$
