Low freezing point vs high freezing point
Web11 jul. 2011 · One factor that influences this freezing point is the strength of the attractive forces between the molecules – the stronger the forces, the higher the freezing point. … The freezing point is the temperature at which the liquid solvent and solid solvent are at equilibrium, so that their vapor pressures are equal. When a non-volatile solute is added to a volatile liquid solvent, the solution vapour pressure will be lower than that of the pure solvent. As a result, the solid will reach equilibrium with the solution at a lower temperature than with the pure solvent…
