Vedclass · Answer

(D) The semipermeable membrane $(SPM)$ allows only solvent molecules to pass through it,not the solute ions ($Fe^{3+}$,$Cl^-$,$K^+$,$[Fe(CN)_6]^{4-}$).Since the solute ions cannot cross the $SPM$,they cannot come into contact with each other to react and form the blue-colored complex (Prussian blue).Osmosis involves the movement of solvent molecules from a region of lower solute concentration to a region of higher solute concentration,but this does not facilitate the mixing of the solutes themselves.Therefore,no reaction occurs,and no blue color is formed.

$FeCl_3$ reacts with $K_4[Fe(CN)_6]$ in aqueous solution to give a blue color. These solutions are separated by a semipermeable membrane $(SPM)$ as shown in the figure. Due to osmosis,there is:
