What happens to the osmotic pressure, boiling point, and freezing point of a solution when the concentration of the solute is decreased?
A)Osmotic pressure increases, boiling point increases, and freezing point increases.
B)Osmotic pressure decreases, boiling point increases, and freezing point decreases.
C)Osmotic pressure decreases, boiling point decreases, and freezing point decreases.
D)Osmotic pressure decreases, boiling point decreases, and freezing point increases.
E)Osmotic pressure increases, boiling point decreases, and freezing point increases.

Question

Quizplus · Accepted Answer

Osmotic pressure is directly proportional to the concentration of the solute, so as the concentration decreases, so does the osmotic pressure (Choice D). Boiling point elevation and freezing point depression are also directly proportional to the concentration of the solute, so as the concentration decreases, both boiling point and freezing point will also decrease (Choice D).
