Evaporation

• Method:

  1. Pour the solution into an evaporating dish
  2. Slowly heat the solution.
  3. The solvent will evaporate and the solution will get more concentrated.
  4. Crystals will start to form.
  5. Keep heating the evaporating dish until all you have left are dry crystals.
• Evaporation is a really quick way of separating a soluble salt from a solution, but you can only use it if the salt doesn’t decompose when it’s heated.
