Potassium sulphate $\left({\mathrm{K}}_2{\mathrm{SO}}_4\right), \mathrm{i}=3$

Sodium chloride $\left(\mathrm{NaCl}\right), \mathrm{i}=2$

Urea, $\mathrm{i}=1$

Glucose, $\mathrm{i}=1$

Greater the value of $\mathrm{i}$, greater lowering in freezing point and hence, lower will be the freezing temperature.

Therefore, ${\mathrm{K}}_2{\mathrm{SO}}_4$ solution has the lowest freezing point.
