Question

Which of the following statement is not correct?

• A. Osmotic pressure $(\pi)$ of a solution is given by the relation $\pi = MRT$ where M is the molarity of the solution.
• B. The correct order of osmotic pressure for $0.2$ M aqueous solution of each solute is $CaCl_{2} > NaCl > CH_{3}COOH > glu\cos e$
• C. Two solution of sucrose of same molality prepared in different solvent will have same elevation in boiling point.
• D. Relative lowering in vapour pressure of a solution containing non volatile solute is directly proportional to mole fraction of solute is Raoult’s law.

Answer 1

Answer: (C)

Two solution of sucrose of same molality prepared in different solvent will have same elevation in boiling point.

Answer 2

With different solvents the coligative properties change
