The main reason is simply one of dichotomy: either a substance is pure or it is not pure. If it is not pure then it consists of two (or more) substances which are chemically separate - a mixture.

What can be classified as a substance?
A substance can be classified as a form of matter that has a specific chemical composition and properties. This includes elements, compounds, and mixtures. Examples of substances include water (H2O), salt (NaCl), and air (a mixture of gases).

How is matter classified into mixtures?
A mixture differs from a compound in that is not chemically bonded together. The mixture is generally mechanically combined, which may be as simple as stirring, or as intensive as using centrifuge to combine the parts.
What are the two principle ways to classify matter?
Matter can be classified as either a pure substance or a mixture. Pure substances are further classified as elements (composed of only one type of atom) or compounds (composed of two or more types of atoms chemically bonded). Mixtures are classified as homogeneous (uniform composition) or heterogeneous (non-uniform composition).
What sample of matter is classified as a solution?
A solution is considered a homogeneous mixture of two or more substances; solutions are generally liquids but sometimes solid. For gases the term is not so adequate.
What is matter made up of two substances not chemically combined?
