Mixtures A mixture contains elements or compounds that are not chemically joined together. You can use physical processes to separate them into substances
Chromatography Separate liquids of different colours. Inks paints and foods often contain mixtures of coloured compounds. Chromatography is used to find out which coloured compounds and mixture contains
Distillation Separate liquids with different boiling points. Distillation can be used to separate compounds with different boiling points. This includes a liquid from dissolved solids and different liquids. Simple distillation evaporate to solvent away leaving the solute. The vapour is then condensed and collected
