How does purity affect melting point
WebImpurities lowers the melting point and increase the boiling point. This is due to the reason that it stabilizes the liquid phase and make it more energetically favorable. Then it extends liquid range to lower temperatures and gaseous molecules to higher temperatures. The above points clearly explains the effect of impurities on boiling point.
