Vedclass · Answer

(A) The freezing point depression is given by $\Delta T_f = i 	imes K_f 	imes m$. The freezing point of the solution is $T_f = T_f^\circ - \Delta T_f$. To have the minimum freezing point,the solution must have the maximum value of the van't Hoff factor $(i)$ multiplied by molality $(m)$.$A: 0.01 \ M \ NaCl \implies i=2, m=0.01, i 	imes m = 0.02$$B: 0.005 \ M \ C_2H_5OH \implies i=1, m=0.005, i 	imes m = 0.005$$C: 0.005 \ M \ MgI_2 \implies i=3, m=0.005, i 	imes m = 0.015$$D: 0.005 \ M \ MgSO_4 \implies i=2, m=0.005, i 	imes m = 0.010$Comparing the values of $i 	imes m$,$0.01 \ M \ NaCl$ has the highest value,therefore it will have the maximum depression in freezing point and the minimum freezing point.
