Q. The depression in freezing point of $0.1\, M$ aqueous solutions of $HCl$, $CuSO_4$ and $K_2SO_4$ are in the ratio

AIIMSAIIMS 2017Solutions

Solution:

$\Delta$Tf = iKfm
Thus, $\Delta$Tf $\propto$ i (as concentration is same for all solutions)
i for HCl = 2, i for CuSO4 = 2, i for K2SO4 = 3 Thus, ratio of depression in freezing point
= 2 : 2 : 3 = 1 : 1 : 1.5
