Chemical Properties of ammonia gas
1. When dissolved in water it
forms an alkali ammonium hydroxide.
NH3 + H2O → NH4OH
2. Ammonia reacts with acids
to form salt.
2NH3 + H2SO4 → (NH4)2SO4
3. Aqueous solution of
ammonia(Ammonium Hydroxide) reacts with acids to form salt and water
NH4OH + HCl → NH4Cl + H2O
4. When ammonia reacts with
hydrogen chloride, solid ammonium chloride is formed.
NH3 + HCl → NH4Cl
5. If ammonia is heated with
carbon dioxide under pressure and temperature of 1500oC, a chemical
fertilizer urea is formed.
2NH3 + CO2 → NH2CONH2 + H2O
6. If ammonia is reacted with
oxygen, nitrogen gas is formed
4NH3 + 3O2 → 2N2 + 6H2O
Uses of ammonia gas:
2. Ammonia is used to make blue prints of land maps
3. It is used in production of chemical fertilizers like urea, ammonium sulphate, ammonium phosphate etc
4. It is used in manufacturing of nitric acid
5. It is used in plastic production
6. It is used to make washing soda
7. It is used as cleansing agent to wash grease
8. It is used on manufacturing of ammonium chloride which is electrolyte of dry cell
