  • Sand + sugar solution
• Separating immiscible liquids


  1. Pour into a separating funnel

  2. Allow layers to separate

  3. Drain off the bottom layer

  • Oil and water
• Separating immiscible liquids by decantation

  1. Carefully pour off the top layer

  2. Leave the other layer behind
• Miscible substances


  Substances which mix together completely
• Separating miscible substances


  Simple distillation - Evaporation followed by Condensation
• Separation of miscible substances is based on their different boiling points
