A mixture is actually made up of pure substances only. But they get mixed with each other in a mixture. Sometimes the individual pure substances are more important than the mixture. Thus, separation of substances is necessary to obtain pure substances for domestic purposes, industrial purposes and research work. Mixtures are substances that retain the properties of their constitutional components. Mixtures with uniform compositions are also called homogeneous mixtures; non-uniform composition mixtures are called heterogeneous mixtures.
