simple 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
• There is another type of distillation called fractional distillation
• Fractional distillation


  Will be looked at in the next video
• 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. Liquid collected in the beaker
• Simple distillation can be used to produce drinking water from sea water
• A great deal of energy is required for simple distillation, so it is generally not used to produce drinking water
• Other techniques are used instead of simple distillation to produce drinking water
