Mixtures

Mixtures

1. Two or more Elements or compounds that are not chemically combined

   • Chemical properties are unchanged
   • Distillation / filtration / crystallisation

2. Ways to seperate

   • Filltration = sand and salt , salt is souluble and sand solvent
   • Crystallisation = salt from salt soulution, evaporating
   • Distillation = prue water, boiling and then condencing

3. Chromatography
