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

A) Solutes raise the boiling point of a solvent.

Explanation:

When the solutes are added into solvents boiling point of solvents increases.

Consider the example of NaCl in water:

The water boil when the molecules of water overcome the surrounding pressure and turn into gaseous phase.

But when we added the the salt it splits into the anion and cation and intermolecular forced between water molecules altered. The di pole is created one side becomes positive and other becomes negative. This di pole interaction is stronger than hydrogen bonding. So more energy in required to move the particles apart from each other.

Thus boiling point increases and compared to pure water.
