Processes used in separation of a substance into its components and the removal of impurities.
Methods of separation include:
1. Paper chromatography - used in food industry to identify chemicals namely food coloring agents or inks.
2. Filtration - commonly used to separate an insoluble solid from a liquid e. g. sand from water.
3. Evaporation - used in separating a mixture of a soluble solid and a solvent through heating until the solvent evaporates leaving behind the solid residue.
5. Magnetism - used to separate a mixture of two solids with one of them having magnetic properties. Gold can be separated from iron using this method.
