Lesson Notes

Crystallization

1.       Making a substance pure

2.      Solution should be saturated

3.       Change of state of substance from aqueous (aq) to solid.  (Solution was dissolved in water)

Chromatography

1.     To separate a mixture

2.    Find out number of components

3.     Depends on solubility of compounds or substances in a solvent

Green ink is less soluble thus it would choose to stay on the chalk and won’t move up as quickly

Red ink is more soluble thus it would move up with the water up the chalk

Filtration

1. Differentiate between differently-sized substances
