Which of the following is TRUE about colligative properties? Select one: A. Molarity is used to predict increased boiling point because it is temperature-independent. O B. Upon gradually lowering the temperature, water freezes faster than a dilute Nacl solution. C. A more concentrated solution requires lower pressure to stop water diffusion because it has higher amount of solute. O D. A 1:1 (v/v) ethanol-water mixture is less volatile than pure water alone.
