Vedclass · Answer

(C) The freezing point depression is given by $\Delta T_f = i \cdot K_f \cdot m$, where $i$ is the van't Hoff factor and $m$ is the molality.For complete dissociation, $i$ equals the number of ions produced per formula unit.$(a)$ $KCl ightarrow K^+ + Cl^-$, $i = 2$. $\Delta T_f = 2 	imes 0.2 = 0.4 	ext{ m}$.$(b)$ $NaCl ightarrow Na^+ + Cl^-$, $i = 2$. $\Delta T_f = 2 	imes 0.1 = 0.2 	ext{ m}$.$(c)$ $AlPO_4 ightarrow Al^{3+} + PO_4^{3-}$, $i = 2$. $\Delta T_f = 2 	imes 0.05 = 0.1 	ext{ m}$.$(d)$ $MgSO_4 ightarrow Mg^{2+} + SO_4^{2-}$, $i = 2$. $\Delta T_f = 2 	imes 0.15 = 0.3 	ext{ m}$.Comparing the values, $0.1 	ext{ m}$ is the minimum value, which corresponds to $0.05 	ext{ m Aluminium phosphate}$.

Which of the following aqueous solutions exhibits the minimum freezing point depression upon complete dissociation?
