Methods of Separating Mixtures

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.

• chromatography

• distillation

• sieving

• physical manipulation

This method is used to separate metals from non metals.

• use of magnet

• physical manipulation

• sieving

• chromatography

This method is useful in a pharmaceutical industry in determining the amount of each chemical in each product.
