Answer:
When two or more substances, that do not react chemically, are blended together,
the result is a mixture in which each component retains its individual identity and
properties.
The separation of the components of a mixture is a problem frequently encountered
in chemistry. The basis of the separation is the fact that each component has a
different set of physical and chemical properties. The components are pure substances
which are either elements or compounds. Under the same conditions of pressure and
temperature, the properties of every sample of a pure substance are identical. Each
sample melts at the same temperature, boils at the same temperature, has the same
solubility in a given solvent, etc.
