Chemistry Question on Colligative Properties
The depression of freezing point is directly proportional to
A
mole fraction of the solution
B
molarity of the solution
C
molality of the solution
D
molarity of the solvent
Answer
molality of the solution
Explanation
Solution
ΔTf=Kfm ∴ΔTf∝m (molality of the solution ) Hence the lowering in vapour pressure will be maximum
