4.7.5.5 (HT only) Oxidation is the loss of electrons and reduction is the gain of electrons. During electrolysis, at the cathode (negative electrode), positively charged ions gain electrons and so the reactions are reductions. At the (positive electrode), negatively charged ions lose electrons and so the reactions are oxidations. Explain reduction and oxidation in terms of gain or loss of electrons. Write ionic equations for displacement reactions. Identify in a given reaction, symbol equation or half equation which species are oxidised and which are reduced. 1 Write balanced symbol equations/half equations for the displacement of metal oxides. Use these to identify which species has been oxidised or reduced. Give reasons for your answers. WS 1.2 Identify, in a reaction, symbol equation or half equation, which species are oxidised and which are reduced. Carry out simple displacement reactions. Write ionic equations for these reactions.
