- Chemical substances occur in nature in impure stage.
- Also, chemical substances synthesized in the laboratory are obtained in crude and impure form.
- Impurities present in the chemical substances may interfere with the properties to be determined (e.g. melting point or boiling point).
- Therefore, before investigating composition and properties of a given chemical substance, it is important to obtain it in the pure form.
