Question

A compound 'X' of sodium is used as an antacid and it decomposes on strong heating. Name the compound ‘X’ and give its chemical formula.

Answer 1

Antacid:
They are bases that are mild.

Decomposition reaction:

A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products.

Name of the compound ‘X’:

The compound X is Sodium Bicarbonate/ Sodium hydrogen carbonate.

Chemical formula:

${\mathrm{NaHCO}}_3$

On heating:

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

Therefore, Sodium Bicarbonate is used as an antacid and it decomposes on strong heating.
