Question

$FeC{l}_3$ on reaction with $K_4\left[Fe\right(CN{)}_6]$ in aqueous solution gives blue colour. These are separated by a semipermeable membrane AB as shown. Due to osmosis, there is:

• A. Blue color formation in side X.
• B. Blue color formation in side Y.
• C. Blue colour formation in both of the sides X and Y
• D. No blue colour formation.

Answer 1

The correct option is D No blue colour formation.

During osmosis, the only solvent flows from one compartment to other compartments through the semipermeable membrane.

Ions cannot flow through the semipermeable membrane.

Hence, there is no reaction between $FeC{l}_3$ and $K_4\left[Fe\right(CN{)}_6]$.

Hence, no blue colour is formed.

Hence, the correct option is $D$
