Quizplus · Accepted Answer

Colligative properties depend on the concentration of solute particles in a solution, rather than their identity. Osmotic pressure, freezing point depression, and boiling point elevation are all examples of colligative properties. Vapor pressure and density are not affected by the concentration of solute particles, thus they are not colligative properties. Therefore, the correct answer is B, as osmotic pressure and freezing point depression are colligative properties.
