|
A mixture consists of two or more elements or compounds not chemically combined together. |
|
What is a mixture? |
|
|
|
The chemical properties of each substance in the mixture are unchanged. |
|
What happens to the chemical properties of each substance in a mixture? |
|
|
|
Mixtures can be separated by physical processes such as filtration, crystallisation, simple distillation, fractional distillation and chromatography. These physical processes do not involve chemical reactions and no new substances are made. |
|
When mixtures are separated by physical processes how does this affect the chemical reactions and substances made? |
|
|
|
Students should be able to describe, explain and give examples of the specified processes of separation. |
