Key Points: Depression of Freezing Point

Freezing point of solution is smaller than that of pure solvent and is given by

ΔTf = Kf × m

Kf = Metal depression constant or cryoscopic constant

where, \[\Delta T_{\mathbf{f}}=T_{\mathbf{f}}^{\circ}-T_{\mathbf{f}}\]

\[\Delta T_\mathrm{f}=\frac{\mathrm{K}_f\times W_2\times1000}{M_2\times W_1}\]
