Solution

Q.
Of the following 0.10 m aqueous solutions, which one will exhibit the largest freezing point depression [2014]

1 KCl

2 $C_{6} H_{12} O_{6}$

3 ${Al}_{2} {({SO}_{4})}_{3}$

4 $K_{2} {SO}_{4}$

Ans.
(3)

$Δ T_{f} = i \times K_{f} \times m$

So, $Δ T_{f} \propto i$ (van’t Hoff factor)

Salt $i$

KCl 2

$C_{6} H_{12} O_{6}$ 1

${Al}_{2} {({SO}_{4})}_{3}$ 5

$K_{2} {SO}_{4}$ 3

Hence, $i$ is maximum, i.e., 5 for ${Al}_{2} {({SO}_{4})}_{3}$
