A mixture is made up of two or more substances that are not chemically combined together.
The components of a mixture can be separated by physical processes such as filtration, distillation, evaporation, crystallisation and chromatography.
Filtration involves passing the mixture through a filter to separate solids from liquids.
The components of a mixture can be separated by physical processes such as filtration, distillation, evaporation, crystallisation, chromatography and centrifugation.
Distillation separates mixtures based on differences in boiling points.
Distillation separates mixtures based on their boiling points.
Crystallization uses cooling to remove solutes from solutions.
Evaporation involves heating the mixture until some of its component(s) evaporate(es), leaving behind other components.
Distillation involves heating the mixture until it vaporises and then condensing the vapour back into liquid form.
Crystallisation allows insoluble salts to form crystals which can then be filtered out.
Crystallisation involves dissolving a solid substance in a solvent and then cooling the solution so that the solute crystallises out of the solution.
