Question

Two solutions (A) containing $FeC{l}_3\left(aq\right)$ and (B) containing $K_4\left[Fe\right(CN{)}_6]$ are separated by semipermeable membrane as shown below. If $FeC{l}_3$ on reaction with $K_4\left[Fe\right(CN{)}_6]$, produces blue colour of $F{e}_4\left[Fe\right(CN{)}_6]$, the blue colour will be noticed in

• A. (A)
• B. (B)
• C. in both (A) and (B)
• D. neither in (A) nor in (B)

Answer 1

Answer: (D)

neither in (A) nor in (B)

Option (D) is correct.
The blue colour is of the complex of ferro ferricyanide and not of the solvent. But in osmosis only solvent particles move.
