Question

Give two important uses of washing soda and baking soda.

Answer 1

Uses of washing soda:

$\bullet$ In glass, soap, and paper industries.
$\bullet$ To remove permanent hardness of water.

Uses of baking soda:

$\bullet$ As a powder used for baking.
Baking powder is a mixture of baking soda and a mild acid known as tartaric acid. When heated or mixed with water, this mixture releases ${\text{CO}}_2$ gas that makes bread or cake fluffy.
$\bullet$ In fire extinguishers.
In soda-acid fire extinguishers, baking soda reacts with hydrochloric acid to release ${\text{CO}}_2$ gas.
