8. Study of Compounds — B. Ammonia
Ammonia: its laboratory preparation from ammonium chloride and collection; ammonia from nitrides like Mg₃N₂ and AlN and ammonium salts. Manufacture by Haber's Process; density and solubility of ammonia (fountain experiment); aqueous solution of ammonia; its reactions with hydrogen chloride and with hot copper (II) oxide, lead (IV) oxide and chlorine; the burning of ammonia in oxygen; uses of ammonia.
- Laboratory preparation from ammonium chloride and collection; (the preparation to be studied in terms of, setting of the apparatus and diagram, procedure, observation, collection and identification).
- Ammonia from nitrides like Mg₃N₂ and AlN using warm water. Ammonia from ammonium salts using alkalis. The reactions to be studied in terms of reactants, products, conditions and equations.
- Manufacture by Haber's Process.
- Density and solubility of ammonia (fountain experiment).
- The burning of ammonia in oxygen.
- The catalytic oxidation of ammonia (with conditions and reaction).
- Its reactions with hydrogen chloride and with hot copper (II) oxide, lead (IV) oxide and chlorine (both chlorine in excess and ammonia in excess). All these reactions may be studied in terms of reactants, products, conditions, equations and observations.
- Aqueous solution of ammonia - reaction with sulphuric acid, nitric acid, hydrochloric acid and solutions of iron(III) chloride, iron(II) sulphate, lead nitrate, zinc nitrate and copper sulphate.
- Uses of ammonia - manufacture of fertilizers, explosives, nitric acid, refrigerant gas (Chlorofluoro carbon – and its suitable alternatives which are non-ozone depleting), and cleansing agents.
- Tests for ammonia.
