Separating Mixtures

Separating Mixtures

1. chromatography

   • physical method of separation and colourful compounds
   • ink, dyes and colourful agents in food

2. crystilisation

   • evaporating
     • boiling points
   • crystilisation is done by heating the solution so the liquid evaporates
   • washed with cold water to remove impurities

3. fractional distillation

4. hrdrocarbons

   • hydrogen+carbon

5. distillation

   • heating-evaporating-cooling-condensing

6. filtration

   • used to separate solids from liquids
