Types of Mixtures
- Mixtures can contain elements and / or compounds
- Each constituent of the mixture retains its chemical properties
- The parts of a mixture are not chemically bonded together and so they can be separated by physical means
- The choice of the method of separation depends on the nature of the substances being separated
- All methods rely on there being a difference in a physical property such as the boiling point or solubility, between the substances being separated
Exam Tip
A physical method of separation does not produce a new substance as there is no chemical reaction taking place since no chemical bonds are being broken or formed.
