Chromatography and Distilation

Chromatography and Distilation

1. Chromatography

   • How to do it
     • Put bits of ink on filter
       • The separate parts of the ink separate
   • How it works
     • Chromatography works because different dyes will move up the paper at different rates
     • Some will stick to the paper and others will dissolve more readily in the solvent and travel more quickly
     • The distance the dyes travel up the paper depends on the solvent and the paper you use

2. Distilation

   • How to do it
     • heat the solution
       • cool the gas that it produced
   • Used to separate solutions
     • Different liquids will have different boiling points
   • Same concept as fractional distilation
