WebImpurities in the solution increase the boiling point. This is because impurities decrease the water molecules available for vaporisation during boiling. A greater amount of heat is … WebWhat is the effect of impurities on boiling point of water ? Hard Solution Verified by Toppr If we add impurities to a solution boiling point of the solution increases. This happens because the presence of impurities decreases the number of water molecules available to be vaporized during boiling. WebIt’s not difficult to understand how impurities affect the melting point. Foreign substances in a crystalline solid disrupt the repeating pattern of forces that hold the solid together.
