   • Crystilisaion
     • The solution is warmed in an open container, allowing the solvent to evaporate, leaving a saturated solution. A solution that has as much solid dissolved in it as it can possibly contain is called a saturated solution. As the saturated solution is allowed to cool, the solid will come out of the solution and crystals will start to grow. The crystals can then be collected and allowed to dry.
   • fractional distilisation
   • Filtration
     • The mixture of the solid and liquid is placed into the filter paper. The liquid flows through the filter paper and in to the container. The liquid in the container is called the filtrate. The solid that remains in the filter paper is called the residue. The residue can be dried by spreading it out on the filter paper and allowing the liquid to evaporate.
   • chromotography
