(i) Two different solutions of sucrose of the same molality prepared in different solvents will have the same depression in freezing point.

(ii) The osmotic pressure of a solution is given by the equation Π = CRT (where C is the molarity of the solution).

(iii) Decreasing order of osmotic pressure for 0.01 M aqueous solutions of barium chloride, potassium chloride, acetic acid and sucrose is BaCl2> KCl > CH3COOH > sucrose.

(iv) According to Raoult’s law, the vapour pressure exerted by a volatile component of a solution is directly proportional to its mole fraction in the solution.

Correct Answer: (i) Two different solutions of sucrose of the same molality prepared in different solvents will have the same depression in freezing point.

Explanation: The depression in freezing point depends upon the molarity of a solution and the solute present in the solution.
