Similarly, many common liquids are heterogeneous mixtures. What do students need to know about mixtures and solutions? There are many forms or sorts of mixtures, but what is common between all these forms of mixtures is that all substances that are used to form mixtures have the same physical properties. The methods of separating heterogeneous mixtures include: sedimentation, decantation, filtration, mechanical separation, separatory funnel separation. A mixture is created when two or more different substances are physically combined and can be separated back into its original substances.
