WebApr 4, 2024 · The freezing point depression caused by an electrolyte is larger than that of a non-electrolyte at the same molality (i.e., moles of solute per kilogram of solvent). This is due to the fact that electrolytes when dissolved into water dissociate into ions, thus generating more particles in solution.
