Vedclass · Answer

(C) Side $x$: $K_4[Fe(CN)_6] ightarrow 4K^+ + [Fe(CN)_6]^{4-}$. The van't Hoff factor $i = 5$. The effective concentration is $0.1 \ M 	imes 5 = 0.5 \ M$.Side $y$: $FeCl_3 ightarrow Fe^{3+} + 3Cl^-$. The van't Hoff factor $i = 4$. The effective concentration is $0.1 \ M 	imes 4 = 0.4 \ M$.Osmotic pressure is given by $\pi = iCRT$. Since the temperature and concentration of the solute are the same, the osmotic pressure depends on the van't Hoff factor $i$.Since $i_x > i_y$, the osmotic pressure of side $x$ is greater than that of side $y$ $(\pi_x > \pi_y)$.Therefore, the solution on side $y$ has a lower osmotic pressure and is considered hypotonic relative to side $x$.

At $27^{\circ}C$, $0.1 \ M$, $1 \ L$ $K_4[Fe(CN)_6]$ 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 statements is correct?
