Separating Mixtures 2

This method is a technique used in separating a less-dense substance from a denser one.

• decantation

• evaporation

• distillation

• filtration

This technique is based on the differences of the boiling point of the substance in the mixture.

• decantation

• distillation

• filtration

• chromatography

This involves using a strainer or a big screen to separate the components of solid mixtures.
