Different Methods of Separating Mixtures

Question 1

Takes advantage of physical properties such as color and shape.

Answer 1

Mechanical Separation

Question 2

Takes advantage of the physical property of magnetism.

Answer 2

Magnetic Separation

Question 3

Takes advantage of the physical property of the state of matter. A filter can also be used to separate solid particles of different sizes.

Answer 3

Filtration

Question 4

To pour off a liquid, leaving another liquid or solid behind. Takes advantage of differences in density.

Answer 4

Decanting

Question 5

The separation of a mixture of liquids based on the physical property of boiling point.

Answer 5

Distillation

Question 6

Vaporizing a liquid and leaving the dissolved solids behind. Used to separate salt solutions.

Answer 6

Evaporation

Question 7

More dense components sink to the bottom and less dense components float.

Answer 7

Density Separation

Question 8

Circular motion helps denser components sink to the bottom faster.

Answer 8

Centrifuge

Question 9

Uses the property of molecular attraction to separate a mixture. Different molecules have different attractions for the paper vs. the solvent.

Answer 9

Paper Chromatography
