Explain why each species has been oxidised or reduced. 4.7.3.1 cont. react with some metal carbonates to produce salts, water and carbon dioxide. The test for carbon dioxide uses an aqueous solution of calcium hydroxide (limewater). Recall that react with metal carbonates. Write equations predicting products from given reactants. Describe test to identify carbon dioxide. 1 Using common reactants, predict the products. Investigate the reactions between acids and metal carbonates. Write word and balanced symbol equations for these reactions. Video clips: 4.7.3.2 Acids are neutralised by alkalis (eg soluble metal hydroxides) and bases (eg insoluble metal hydroxides and metal oxides) to produce salts and water, and by metal carbonates to produce salts, water and carbon dioxide. The particular salt produced in any reaction between an acid and a base or alkali depends on: Define the term neutralisation. Predict products from given reactants. Use the formulae of common ions to deduce the formulae of salts. 1 Predict products from reactants. WS 1.2 Use the formulae of common ions to deduce the formulae of salts.
