Question

Q5) Salt A commonly used in bakery products on heating gets converted into another salt B which
itself is used for removal of water and a gas C is evolved. The gas C when passed through lime
water turns it milky.
a) write the chemical equations involved in these reaction​

Answer 1

Answer:

Baking power which is a salt is used as bakery products which give sodium carbonate and carbon dioxide gas on heating. Sodium carbonate is used to remove the hardness of water. Carbon dioxide turns lime water milky.

NaHCO 3 (Sodium bicarbonate) → Na 2 CO3 (Sodium carbonate) + CO 2(carbon dioxide) + H 2O

Therefore,

Salt A, which is sodium bicarbonate and used as baking powder.

Salt B is sodium carbonate, which is used to remove the hardness of water.

C is carbon dioxide gas which turns lime water milky.
