Which of the following statements is false?
(i) Two different solutions of sucrose of 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.
