Colligative properties, Depression of freezing point (DFP)

Question

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

Easy

A

KCl
B

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

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

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

Solution

$Δ T_{f} = i \times K_{f} \times m$
$So, Δ T_{f} \propto i (van't Hoff factor)$
$Hence, i is maximum i.e., 5 for {Al}_{2} {({SO}_{4})}_{3} .$
