ways of seperation

ways of seperation

1. dissolving

   • this is not a way of seperation but a process in the substance that is seperated

2. distillation

   • boil the mixture of solute and solvent
   • catch the vapour that evolves off the surface
   • your are left with the solute

3. chromotography

   • this uses a solvent to seperate mixtures
   • as the solvent travels up the chromotography paper different parts of the mixture will move up at different rates
   • relention facor
   • rf=distance moved by the compound divided by distance moved by the solvent

4. filtration

   • filtering the mixture means that only one substance goes through-the smaller one
   • water and marb]es- the marbles would be left behind
     • water and dissolved sugar-nothing would stay behind
