Which one of the following statements is false ?

A

The correct order of osmotic pressure for 0.01 M aqueous solution of each compound is `BaCl_2 gt KCl gt CH_3COOH gt` socrose.

B

Isotonic solutions are those solutions which have the same osmotic pressure.

C

Raoult's law states that the vapour pressure of a component over a solution is proportional to its mole fraction in liquid state.

D

Two sucrose solution of same molality prepared in different solvents will have the same freezing point depression.

Text Solution

Verified by Experts

The correct Answer is:
D
Depressionin freezing point `= K_f m(as K_f uarr,DeltaT_f uarr)`
`K_f` depends upon the solvent
