Question:
Which one of the following $0.10 \mathrm{M}$ aqueous solutions will exhibit the largest freezing point depression?
Correct Option: , 4
Solution:
$\because$ Van't Hoff factor is highest for $\mathrm{KHSO}_{4}$
$\therefore$ colligative property $\left(\Delta \mathrm{T}_{f}\right)$ will be highest for $\mathrm{KHSO}_{4}$
