2.5 separation

2.5 separation

1. extraction

   • used for the difference in solubility
   • for example sand and salt

2. filtration

   • used for the difference in particle size
   • for example sand and salt

3. evaporation

   • used for the difference in boiling points
   • for example sand and salt

4. distillation

   • used for the difference in boiling points
   • difference with evaporation= distillation keeps all the liquids
   • for example wine

5. chromatography

   • used for difference in adhesion and solubility
   • to determine the composition of a color

6. adsorption

   • used for the difference in adhesion.
   • norit
   • to remove dyes, fragrances, toxins and flavors
