4.1 Oxidation and reduction Oxidation as gain of oxygen and reduction as loss of oxygen, metals reacting with oxygen to form oxides, and identifying which substance is oxidised and which is reduced in a redox reaction. AQA Edexcel OCR 4.2 The reactivity series and displacement The order of reactivity of metals including carbon and hydrogen, how metals react with water and dilute acids, displacement reactions, and how reactivity relates to the tendency of a metal to form positive ions. AQA Edexcel OCR 4.3 Extracting metals with carbon Why unreactive metals are found as elements, how metals less reactive than carbon are extracted by reduction with carbon, why more reactive metals are extracted by electrolysis, and how cost affects the method used. AQA Edexcel OCR 4.4 Oxidation and reduction in terms of electrons Oxidation as loss of electrons and reduction as gain of electrons (OIL RIG), writing ionic equations and half equations for displacement reactions, spectator ions, and identifying what is oxidised and reduced.
