A solute added to a solvent raises the boiling point of the solution because:


▸ the temperature to cause boiling must be great enough to boil not only the solvent but also the solute.

▸ the solute particles lower the solvent's vapor pressure, thus requiring a higher temperature to cause boiling.

▸ the solute particles raise the solvent's vapor pressure, thus requiring a higher temperature to cause boiling.

▸ the solute increases the volume of the solution, and an increase in volume requires an increase in the temperature to reach the boiling point (derived from PV = nRT).

▸ two of these are correct.
