Explain why melting and boiling points can be used as a way to check purity.[2]

Answer» ONG>Explanation:

Fractional distillation is a technique used to separate impurities. - Usually impurities have lower melting/boiling POINT, THUS evaporates earlier can be removed. - However, purecompounds have high melting/boiling POINTSAND evaporates very slowly. - This is how wecan CHECK purity of compounds
