Which of the statements about the effect of solutes on solutions is true Select one:
O a. Solutes raise the boiling point of a solvent.
O b. Water with a solute dissolved in it will freeze at 0°C.
O c. Solutes raise the freezing point of a solvent
d. Antifreeze boils at a lower temperature than pure water.

Solutes raise the boiling point of a solvent.

Explanation:

When the solutes is non volatile and dissolved in a solvent, it lowers the vapour pressure of the solvent hence elevating the boiling point of the solvent.
