Pure elements and compounds melt and boil at specific temperatures. Melting and boiling point data can be used to distinguish pure substances from mixtures. In everyday language, a pure substance can Explain what is meant by the purity of a substance, distinguishing between the scientific and everyday use of the term ‘pure’. 0.5 WS 3.5 Use melting point data to distinguish pure from impure substances. Pupils investigate the effect of table salt on the melting point and boiling point of water.
