Question

why impurities lower the boiling point ​

Answer 1

Answer:

Impurities in solids typically lower the melting point because they disrupt the pristine crystal lattice. Adding impurities to a liquid typically raises the boiling point because of increased solution phase entropy. Or you can think of the impurity as lowering the vapor pressure of the liquid.
