Question

Complete the following equation:

${\mathrm{NaHCO}}_3+\mathrm{HCl}\stackrel{}{\to }---$

Answer 1

Reaction of sodium bicarbonate with hydrochloric acid:

• Acids react with metal hydrogen carbonates and form corresponding salts, carbon dioxide$\left({\mathrm{CO}}_2\right)$, and water$\left({\mathrm{H}}_2\mathrm{O}\right)$
• For example hydrochloric acid$\left(\mathrm{HCl}\right)$ on reaction with sodium bicarbonate$\left({\mathrm{NaHCO}}_3\right)$ forms sodium chloride$\left(\mathrm{NaCl}\right)$, carbon dioxide$\left({\mathrm{CO}}_2\right)$, and water$\left({\mathrm{H}}_2\mathrm{O}\right)$.
• $\underset{\mathrm{sodium}\mathrm{bicarbonate}}{{\mathrm{NaHCO}}_3\left(\mathrm{aq}\right)}+\underset{\mathrm{hydrochloric}\mathrm{acid}}{\mathrm{HCl}\left(\mathrm{aq}\right)}\stackrel{}{\to }\underset{\mathrm{sodium}\mathrm{chloride}}{\mathrm{NaCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
