Use data to identify pure and impure substances. Identify the contents of mineral waters sold as ‘pure’. Discuss the meaning of ‘pure’. 4.8.1.2 A formulation is a mixture that has been designed as a useful product. Many products are complex mixtures in which each chemical has a particular purpose. Formulations are made by mixing the components in carefully measured quantities to ensure that the product has the required properties. Formulations include fuels, cleaning agents, paints, medicines, alloys, fertilisers and foods. Identify formulations given appropriate information. Students do not need to know the names of components in proprietary products. WS 1.4, 2.2 0.5 Define the terms: mixture formulation.
