Key Stage 2

Meaning

Separating Mixtures is when you take out one of the substances from a mixture.

About Separating Mixtures

Different mixtures need to be separated in different ways:

Examples

Beach Muddy Puddle Sea Water
 
 
 
You can separate the sand from the pebbles with a sieve. You can separate mud from water in the puddle with filter paper and a funnel. You can separate salt from the water by evaporating the water in an evaporating dish.
 
 
 

Key Stage 3

Meaning

Separating Mixtures is when you take out one or more of the substances from a mixture.

About Separating Mixtures

All mixtures can be separated without a chemical reaction.
There are several methods of separating mixtures that you should know:

Examples

Filtration Evaporation
 
 
A mixture or a liquid and an insoluble solid can be separated by filtration. A solute can be recovered from a solution by evaporating away the solvent.
Distillation Chromatography
 
 
The solute and solvent can be separated by distillation. When there are more than 1 solutes in a solution chromatography can separate them.


Key Stage 4

Meaning

To separate a mixture is to remove one or more chemicals from a mixture of chemicals.

About Separating Mixtures

Techniques to separate mixtures are usually used to obtain pure samples of a chemical.

Different separation techniques are needed for different types of mixture:
