Distillation

• Simple distillation

  1. Evaporate the liquid by heating

  2. Condense the vapor back to a liquid by cooling
• Simple distillation


  • Consists of two stages: evaporation and condensation
• Apparatus used for simple distillation

  • Flask containing solution
  • Continuous glass tube
  • Condenser with cold water circulation
  • Thermometer
• Steps in simple distillation

  1. Heat the solution to evaporate the liquid

  2. Vapor rises up the glass tube

  3. Vapor passes through the cold condenser and condenses back to a liquid

  4. Collect the liquid in a beaker
• Diagram for distillation- method of separation that can be used on a soluble solid and its solvent, or

  on two miscible liquids (liquids that mix).
