Question
At $27^{\circ}C,0.1M,1\text{ }L{\text{ }K}_{4}\left\lbrack Fe(CN)_{6} \right\rbrack$ aqueous solution and $0.1M,1\text{ }L{FeCl}_{3}$ aqueous solution are placed in a container separated by a semi permeable membrane AB . Assume complete dissociation of both the solutes. Which of the following statement is correct?
Options
A.Blue color is formed on both sides.
B.Ionic solutes in aqueous solution can pass through semi-permeable membrane.
C.Solution on side ' $y$ ' is hypotonic.
D.To cause the reverse flow of solvent during osmosis, external pressure (any value) should be applied to side ' x '.
Solution
Sol. [Key Concept: Only solvent crosses a semipermeable membrane; both solutions are $0.1$ M, so judge tonicity and the external pressure that reverses osmosis.]
