Physical processes

Either evaporation or crystallisation can be used to separate a solid solute from a solution. Learn more in this KS3 Chemistry guide from Bitesize.

Distillation is a separation technique is used to remove a solvent from a mixture and keep it rather than it mixing with the air and being lost.

Solids, liquids and gases change state when they are heated or cooled. Processes such as evaporation and boiling change the state of substances

Use diagrams to show how scientific apparatus is set up and how to draw them in 2D. Common practical techniques that use apparatus include filtration, evaporation and distillation.

A solution is made when a solute dissolves into a solvent. If a substance can dissolve into a solvent, it is soluble. If it cannot dissolve, it is described as insoluble.

Filtration is used to separate an insoluble solid from a pure liquid or a solution.
