Crystallisation

• Method:

  1. Pour the solution into an evaporating dish and gently heat the solution.
  2. Some of the solvent will evaporate and the solution will get more concentrated.
  3. Once some of the solvent has evaporated (or when you see crystals start to form) remove the dish from the heat and leave it to cool.
  4. Filter the crystals out of the solution and leave them in a warm place to dry.
• You could use a drying oven or a dessicator to dry crystals.
