How does adding a non-volatile solute to a pure solvent affect the boiling point of the pure solvent? the solvent will have a lower boiling point. the solvent will have a higher boiling point. the solvent's boiling point will not be affected. the solvent's boiling point will most likely change, but not in a predictable way.
