Separation OF Mixtures
Many of the materials around us are mixtures. These mixtures have two or more than two substances (or constituents) mixed in them. It may not be possible to use a mixture as such in homes and in industries. We may require only one (or two) separate constituents of a mixture for processes which are commonly used to separate the constituents of mixtures are : Sublimation, Magnet, Solvents, Filtration, Centrifugation, Evaporation, Crystallisation,Chromatography, Distillation, Fractional distillation and Separating funnel.In some cases, more than one of these processes are used for separating a mixture.
In order to learn the separation of mixtures, we will consider the following three cases :
1. Mixture of two solids
2.Mixture of a solid and a liquid
3.Mixture of two liquids
We will now discuss these three cases in detail, one by one.
