When a sodium compound X which is also used in soda-fire extinguisher is heated, gives a sodium compound Y along with water and carbon dioxide. Y on crystallisation forms compound Z. Identify X, Y and Z.
The sodium compound X used in fire extinguisher is Sodium bicarbonate (NaHCO3) and when it is heated it gives sodium carbonate (Na2CO3) as Y along with water (H2O) and carbon dioxide (CO2). Sodium carbonate on absorbs 10 molecules of water and crystallises into sodium decahydrate (Na2CO3.10H2O).
Thus X is Sodium bicarbonate (NaHCO3), Y is sodium carbonate (Na2CO3) and Z is sodium decahydrate (Na2CO3.10H2O).
