MCQ
Which one of the following statements is FALSE
  • A
    The correct order of osmotic pressure for $0.01 M $ aqueous solution of each compound is $BaC{l_2} > KCl > C{H_3}COOH > $ sucrose.
  • B
    The osmotic pressure $(\pi )$ of a solution is given by the equation $\pi = MRT$ where $M$  is the molarity of the solution.
  • C
    Raoult's law states that the vapour pressure of a component over a solution is proportional to its mole fraction.
  • ✓
    Two sucrose solutions of same molality prepared in different solvents will have the same freezing point depression.
✓

Answer

Correct option: D.
Two sucrose solutions of same molality prepared in different solvents will have the same freezing point depression.
d
(d)The extent of depression in freezing point varies with the number of solute particles for a fixed solvent only and it is a characteristics feature of the nature of solvent also. So for two different solvents the extent of depression may vary even if number of solute particles be dissolved.
