Separating Mixtures

1. Crystallisation

2. Chromatograhpy

   • A way to separate soluble substances.
   • Chromatogram-The resulting evidence on paper.
   • Separation- When one substance can move more than another in a liquid, this results in separation between them.

3. Filtration

4. Fractional Distillation

   • Only works if the two substances mixed have DIFFERENT BOILING POINTS.
   • Uses a fractionating column to separate crude oil.

5. Distillation- Evaporation followed by condensation.

   • Fractional- A type of distillation used to separate crude oil.

6. Mixture

   • Mixture- Contains two or more substances that have not reacted chemically with each other.
   • Is made up of little bits of each substance that are just put together.
