# Which one of the following

Question:

Which one of the following $0.10 \mathrm{M}$ aqueous solutions will exhibit the largest freezing point depression?

1. hydrazine

2. glucose

3. glycine

4. $\mathrm{KHSO}_{4}$

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 $\mathrm{KHSO}_{4}$
