Salts of transition metals can be made by reacting an insoluble metal compound with an appropriate acid.
Plan an experiment to prepare a pure, dry sample of copper(II) chloride crystals, CuCl2\text{CuCl}_2CuCl2, starting from a suitable insoluble copper compound and an appropriate acid.
Your plan should include:
276 exam-style questions on Edexcel GCSE Chemistry 4.1 Acids, covering 4.1.1 Acids, alkalis and the pH scale, 4.1.2 Hydrogen ion concentration and pH, 4.1.3 Dilute and concentrated, weak and strong acids, 4.1.4 Bases, alkalis and the reactions of acids, 4.1.5 Chemical tests for hydrogen and carbon dioxide, 4.1.6 Neutralisation as a reaction of acids with bases, 4.1.7 Preparing soluble salts, and 4.1.8 Solubility rules and preparing insoluble salts. Each one has a worked solution and a mark scheme showing where the marks go.
