8. Study of Compounds — D. Sulphuric Acid
Large scale preparation, its behaviour as an acid when dilute, as an oxidizing agent when concentrated - oxidation of carbon and sulphur; as a dehydrating agent - dehydration of sugar and copper (II) sulphate crystals; its non-volatile nature.
- Manufacture by Contact Process (Equations with conditions where applicable).
- Its behaviour as an acid when dilute - reaction with metal, metal oxide, hydroxide, carbonate, hydrogen carbonate, sulphite, hydrogen sulphite and sulphide.
- Sulphuric acid as dibasic acid.
- Concentrated sulphuric acid as an oxidizing agent - the oxidation of carbon and sulphur.
- Concentrated sulphuric acid as a dehydrating agent- (a) the dehydration of sugar (b) Copper (II) sulphate crystals.
- Non-volatile nature of sulphuric acid - reaction with sodium or potassium chloride and sodium or potassium nitrate.
