The depression in freezing point of a solution is________________?
Correct answer: C. Both A. and B.
- A. Inversely proportional to the mass of solvent
- B. Directly proportional to the mole of solute
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
The freezing-point depression is given by ΔTf = Kf m, where molality is moles of solute per kilogram of solvent. It is therefore directly proportional to moles of solute and inversely proportional to the mass of solvent.
