IGCSE CHEMISTRY 
MIXTURES
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:
Atoms (C1-3)
Compounds (C1-3)
Mixtures (C2,3)
C4. Stoichyiometry
C5. Electricity and Chemistry 
C6. Energy Changes in Chemical Reactions
C7. Chemical Reactions
C8. Acids, Bases and Salts
C9. The PeriodicTable
C10. Metals
C11. Air and Water 
C12. Sulphur 
C13. Carbonates 
C14. Organic Chemistry

C1-3 Atoms
C1,2,3 Compounds
