Separating mixtures

• Filtration

  
  

  insoluble solid from a liquid -- sand and water

  Filter paper with small holes
• Distillation

  
  

  Solvent from solution

  Heat solution

  Solvent cools in condensing tube and falls into a beaker
• Fractional distillation

  
  

  Separate different liquids from a mixture

  Liquids have different boiling points

  Fractioning column - where liquids cool and are taken from
• Chromatography

  
  

  Separate mixtures of soluble substances

  Chromatogram produced - used to distinguish pure and impure substances
