Summary of the specification content Learning outcomes What most candidates should be able to do Suggested timing (hours) Opportunities to develop Scientific Communication skills Opportunities to practical and enquiry skills Self/peer assessment Opportunities and resources Reference to past questions that indicate success 4.8.2.1 Metals react with oxygen to produce metal oxides. The reactions are oxidation reactions because the metals gain oxygen. Reduction involves the loss of oxygen. Unreactive metals such as gold are found in the Earth as the metal itself but most metals are found as compounds that require chemical reactions to extract the metal. Knowledge and understanding are limited to the reduction of oxides carbon. Metals less reactive than carbon can be extracted from their oxides by reduction with carbon. Knowledge of the details of processes used in the extraction of metals is not required. Define the terms oxidation and reduction. Explain reduction and oxidation in terms of loss or gain of oxygen, identifying which species are oxidised and which are reduced. Explain, using the position of carbon in the reactivity series, the principles of industrial processes used to extract metals, including extraction of a non-ferrous metal. 1 Write word and balanced symbol equations for the reactions of metals with oxygen to produce metal oxides. Use these to identify where reduction and oxidation has taken place. WS 1.2 Identify the substances which are oxidised or reduced in terms of gain or loss of oxygen. WS 1.4 Explain in terms of the reactivity series why some metals are extracted with carbon and others by electrolysis. WS 1.4 Interpret or evaluate specific metal extraction processes when given appropriate information. Demo reaction: reacting metals with oxygen. Experiment: reduction of iron oxide by carbon.
