1.	Which of the following statements is false? [NCERT Exemplar] (а) Two different solutions of sucrose of same molality prepared in different solvents will have the same depression in freezing point. (b) The osmotic pressure of a solution is given by the equation π = CRT (where C is the molarity of the solution). (c) 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. (d) 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.
Answer» DEPRESSION in freezing depends on CONCENTRATION (molarity) of solution and also on solvent taken.ΔT =(K f)× molarity ↘ depends on solvent takenSo, option (A) is a wrong statementExplanation:PLEASE mark my answer as a BRAIN list and also follow me please like it if it helped you...
