Question:
Which one of the following statements is false?
Which one of the following statements is false?
Show Hint
Colligative properties depend on the nature of solvent constants.
Updated On: Mar 17, 2026
- The correct order of osmotic pressure for 0.01 M aqueous solution of each compound is BaCl₂ > KCl > CH₃COOH > sucrose.
- The osmotic pressure (π) of a solution is given by π = MRT, where M is the molarity of the solution.
- 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.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
- (A) Correct: Osmotic pressure π = iMRT; BaCl₂ dissociates most.
- (B) Correct: This is the van’t Hoff equation.
- (C) Correct: Raoult’s law definition.
- (D) False: Freezing point depression depends on the cryoscopic constant of the solvent, which varies for different solvents.

Top Questions on reaction mechanism
- Given below are two statements:
Statement I: The dipole moment of R–CN is greater than R–NC and R–NC can undergo hydrolysis under acidic medium to produce R–COOH.
Statement II: R–CN hydrolyses under acidic medium to produce a compound which on treatment with SOCl$_2$, followed by the addition of NH$_3$ gives another compound (X). This compound (X) on treatment with NaOCl/NaOH gives a product, that on treatment with CHCl$_3$/KOH/$\Delta$ produces R–NC.
