How does impurity affect solubility

WebDec 30, 2024 · Add a comment 1 Answer Sorted by: 1 Adding impurities (which mostly have low heat capacity, like salt) decreases the enthalpy of vaporization. This is because the impurities lower the heat capacity of the solution as a whole, making the enthalpy of vaporization lesser than the original solvent.
