Chemical properties are used to separate mixtures.

A magnet would be a good tool to use when you need to separate a mixture of iron filings and pepper.

A sieve would be a good tool to use to separate larger pieces from much smaller pieces in a mixture.

All materials will flow through a filter.

Mixtures can be separated when the materials in it have different densities.

To separate a solution (one substance dissolved into a liquid), the liquid can be boiled to separate the two substances.

Sometimes, more than one method of separating a mixture will be needed to separate all the materials in the mixture.

When mixtures are separated, it is a chemical change in matter.
