Salt A commonly used in bakery products on heating gets converted into another salt B which itself is used for removal of hardness of water and a gas C is evolved. The gas C when passed through lime water, turns it milky. Identify A, B and C.
Salt A is sodium bicarbonate (NaHCO3) as it is commonly used in bakery products and on heating produces Na2CO3. Salt B is sodium carbonate Na2CO3 as it is used for removal of hardness of water. Gas C is carbon dioxide (CO2 ) as it turns lime water milky.
This can be shown as a chemical equation:
