  • What is a colligative property?
  • Explain why the freezing point of a solution depresses and boiling point elevates compared to the pure solvent.
  • If the density of milk is 1.035 g/cm3 and the freezing point is -0.5250 ∘C∘C, calculate the freezing point depression constant, Kf, for milk if the temperature of the mixture drops to -0.7750 ∘C∘C. Assume the whipping cream is milk and therefore your pure solvent is milk. The formula for sugar, sucrose, is C12H22O11. Use one dry oz = 28.35 g. Explain how you came to your answer using equations and/or complete sentences.
