Vedclass · Answer

(C) The depression in freezing point $(\Delta T_f)$ is given by the formula $\Delta T_f = i 	imes K_f 	imes m$,where $i$ is the van't Hoff factor,$K_f$ is the cryoscopic constant,and $m$ is the molality.Since $K_f$ and $m$ are constant for all solutions,$\Delta T_f \propto i$.We calculate the van't Hoff factor $(i)$ for each solute:$1. KCl ightarrow K^+ + Cl^-$,so $i = 2$.$2. C_6H_{12}O_6$ (glucose) is a non-electrolyte,so $i = 1$.$3. Al_2(SO_4)_3 ightarrow 2Al^{3+} + 3SO_4^{2-}$,so $i = 5$.$4. K_2SO_4 ightarrow 2K^+ + SO_4^{2-}$,so $i = 3$.Since $Al_2(SO_4)_3$ has the largest van't Hoff factor $(i = 5)$,it will exhibit the largest freezing point depression.

Of the following $0.10 \ m$ aqueous solutions,which one will exhibit the largest freezing point depression?
