Edexcel IGCSE Chemistry Lecture 23 - Acids, Bases and Salts

Powerpoint lecture covering the following in a modern, concise format:

Specification Point 2.34 - Know the general rules for predicting the solubility of ionic compounds in water.

Specification Point 2.35 - Understand acids and bases in terms of proton transfer.

Specification Point 2.36 - Understand that an acid is a proton donor and a base is a proton acceptor.

Specification Point 2.37 - Describe the reactions of hydrochloric acid, sulfuric acid and nitric acid with metals, bases and metal carbonates to form salts.

Specification Point 2.38 - Know that metal oxides, metal hydroxides and ammonia can act as bases, and that alkalis are bases that are soluble in water.

Specification Point 2.39 - Describe an experiment to prepare a pure, dry sample of a soluble salt, starting from an insoluble reactant.

Specification Point 2.42 - Practical: prepare a sample of pure, dry hydrated copper (II) sulphate crystals starting from copper (II) oxide.
