Question 15
Give two important uses of washing soda and baking soda.

Answer 1

Uses of washing soda:

• In glass, soap, and paper industries.
• To remove permanent hardness of water.

Uses of baking soda:

• As a baking powder. Baking powder is a mixture of baking soda and a mild acid known as tartaric acid. When it is heated or mixed with water, it releases $C{O}_2$ that makes bread or cake fluffy.
• In soda-acid fire extinguishers, to release \(CO_2\ gas.
