Depression in freezing point ${\mathrm{\Delta T}}_{\mathrm{f}}=\mathrm{i}.{\mathrm{k}}_{\mathrm{f}}.\mathrm{m}$

For one molal soloution ; ${\mathrm{\Delta T}}_{\mathrm{f}}\propto \mathrm{i}$

$\mathrm{i}$ is least for $\left[\mathrm{Co}{\left({\mathrm{H}}_2\mathrm{O}\right)}_3{\mathrm{Cl}}_3\right].3{\mathrm{H}}_2\mathrm{O}$ ; So ${\mathrm{\Delta T}}_{\mathrm{f}}$  is least but freezing point is high.
