C1 THE PARTICULATE NATURE OF MATTER AND C2 EXPERIMENTAL TECHNIQUES
Before you start you can look back at 8EF Elements, Mixtures and Compounds.
If you only remember one thing:
IN A MIXTURE THE SUBSTANCES ARE NOT CHEMICALLY JOINED. tHEY CAN BE SEPARATED BY (FRACTIONAL) DISTILLATION, FILTRATION, CRYSTALLISATION AND CHROMATOGRAPHY.
This is the third of the 14 Chemistry units:
C5. Electricity and Chemistry
C6. Energy Changes in Chemical Reactions
C7. Chemical Reactions
C8. Acids, Bases and Salts
C9. The PeriodicTable
C11. Air and Water
C14. Organic Chemistry
USEFUL VIDEOS AND PRESENTATIONS
A video from BBC Bitesize showing separation techniques (sorry it is low quality)
A video explaining the basics of separation techniques. It explains how water is purified for drinking too.
Chromatography from Fuse School.
Some distillation demonstrations
Fractional distillation from Fuse School
Uses of crude oil fractions from Fuse School
Separation of liquids that have different densities using a separating funnel.
