At \(27°\)C, \(0.1\) M, \(1\) L \(K_4[Fe(CN)_6]\) aqueous solution and \(0.1\) M, \(1\) 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?
- 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 '\(x\)'.
Answer & Solution
Correct Answer
(C) Solution on side '\(y\)' is hypotonic.
Step-by-step Solution
Detailed explanation
For complete dissociation, the van 't Hoff factor \(i\) is equal to the number of ions produced per formula unit. For side 'x' containing \(K_4[Fe(CN)_6]\): \(K_4[Fe(CN)_6] \rightarrow 4K^+ + [Fe(CN)_6]^{4-}\) Number of ions, \(i_x = 5\) Effective concentration (osmolarity)…
