RankGuru · Accepted Answer

The **Melting Point** is a primary criterion for the purity of solid organic compounds.
- **Pure Solid**: Characterized by a **sharp melting point**, meaning it transitions from solid to liquid over a very narrow temperature range (typically $< 1^\circ C$).
- **Impure Solid**: The presence of even small amounts of impurity lowers the melting point (Melting point depression) and causes the substance to melt over a much **wider temperature range**.
- Identical compounds can be confirmed by 'Mixed Melting Point' - if a mixture of two samples shows no depression or widening of m.p., they are the same substance.
