Question

Which of the following statements is false?
(a) Two different solutions of sucrose of same molality
prepared in diffferent 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 > CH3₃COOH > 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 1

Two different solutions of sucrose of same molality  prepared in different solvents will have the same  depression in freezing point is the false statement.

Explanation:

Depression in freezing point depends on concentration or molarity of solution and also on solvent taken.

ΔTf = Kf × molarity

Osmosis

• It is the diffusion of a liquid or gases which passed to a semipermeable membrane.  
• When a semipermeable membrane which is skins of fruits, animal bladders, and vegetables that separates solvent in the solution, then pass to the membrane by the solvent molecule.
• Solvents flow is required to stop the solutions pressure difference through the semipermeable membrane.
• A solutions osmotic pressure is proportional to the concentration of molarity of the solutions solute particles.

Raoult's law states that the vapor pressure determined by all the elements of individual chemical and the mole fraction that produce the total solution. When the vapor pressure is low which is proportional to concentration.
