RAOULT’S LAW: freezing point depression. “By dissolving a solute in a solvent, the freezing point of the solution is lowered. The reason for this lower freezing point is that when a liquid freezes, the molecules form a pure solid sample of solvent. Those molecules still in the liquid phase still have solute molecules at the liquid-solid surface, so more molecules will go from solid phase to liquid phase.”
