Vedclass · Answer

(C) Osmotic pressure $(\pi)$ is a colligative property given by $\pi = iCRT$, where $i$ is the van't Hoff factor. For equimolar solutions, the osmotic pressure depends on the value of $i$.For $K_4[Fe(CN)_6]$, it dissociates as $4K^+ + [Fe(CN)_6]^{4-}$, so $i = 5$.For $Na_2SO_4$, $i = 3$ $(2Na^+ + SO_4^{2-})$.For $BaCl_2$, $i = 3$ $(Ba^{2+} + 2Cl^-)$.For $Al_2(SO_4)_3$, it dissociates as $2Al^{3+} + 3SO_4^{2-}$, so $i = 5$.For $C_{12}H_{22}O_{11}$ (sucrose), it is a non-electrolyte, so $i = 1$.Since $Al_2(SO_4)_3$ has the same van't Hoff factor $(i = 5)$ as $K_4[Fe(CN)_6]$, it will have the same osmotic pressure.

Which of the following solutions has an osmotic pressure nearest to that of an equimolar solution of $K_4[Fe(CN)_6]$?
