Question

What will happen if a solution of Sodium hydrogen carbonate is heated? Give the equation of the reaction involved.

Answer 1

Sodium hydrogen carbonate:

• It is also called Sodium bicarbonate or baking soda.
• Its formula is ${\mathrm{NaHCO}}_3$.

Heating Sodium hydrogen carbonate:

• When Sodium hydrogen carbonate (${\mathrm{NaHCO}}_3$) is heated, it decomposes into Sodium carbonate (${\mathrm{Na}}_2{\mathrm{CO}}_3$), Carbon dioxide (${\mathrm{CO}}_2$) and water.

$2{\mathrm{NaHCO}}_3\left(\mathrm{s}\right)\stackrel{∆}{\to }{\mathrm{Na}}_2{\mathrm{CO}}_3\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
