  • mixtures are made of two or more substances that haven't been chemically combined
  • Chromotography- seperates solutions with a different number of solutes and solvents
  • solute (a substance being dissolved)
  • solvent (the element dissolving the solute)
  • the solvent moves up the paper and carries the solute with it in the solution
  • Crystilisation (heating the mixture so the solvent evaporates)
  • Filtration-seperating mixtures that are insoluble
