Question

Quizplus · Accepted Answer

When the concentration of the solute is decreased, the osmotic pressure decreases because there are fewer solute particles to attract water molecules. The boiling point and freezing point both decrease because the presence of the solute lowers the vapor pressure and raises the freezing point of the solution. Therefore, decreasing the concentration of the solute will lead to a decrease in both the boiling point and freezing point of the solution.
