Show graphically that freezing point of a liquid will be depressed when a non-volatile solute is dissolved in it.
Answer:
When a non-volatile solid is added to the solvent its vapour pressure decreases and now it would become equal to that of solid solvent at lower temperature. Thus, the freezing point of the solvent decreases
