Question

A compound X of sodium form a white powder it is a constituent of baking powder and is used in some antacid prescriptions. when heated X give out a gas and steam . the gas forms a white precipitate with lime water. write the chemical formula and name of X and the chemical equation for its decomposition on heating. what is it role in baking powder and in antacid? ​

Answer 1

Answer:

X-NaHCO3; Y-NaCO3; Z-CO2

Explanation:

Baking powder(NaHCO3)salt X commonly used in bakery products.On heating ,it forms sodium carbonate (Na2CO3),Y and CO2 gas,Z is evolved when CO2 gas,Z is passed through lime water ,it forms calcium carbonate (CaCO3),which is slightly soluble in water making it milky.

2NaHCO3 heat Na2CO3+H2O+CO2

Na2CO3.10H2O heat Na2CO3+10H2O
