In this tutorial, we are going to discuss about steps of preparing ammonia from calcium cyanamide hydrolysis reaction.
Calcium carbide (CaC2) is heated with nitrogen gas stream at 10000C. It gives calcium cyanamide ( CaNCN) and carbon. This mixture is called nitrolime.
This reaction is a redox reaction (oxidation reduction reaction).
Nitrogen gas is reduced and carbon atoms are in the carbide are oxidized.
Hydrolysis of calcium cyanamide will release ammonia gas slowly. Also calcium carbonate (CaCO3) is given as a product. CaCO3 is deposited as a white precipitate.
Nitrolime is used as a fertilizer.
