Would a 1 aqueous solution of glucose, C6H12O6, or a 1 aqueous solution of the m m ionic compound, (NH4)3PO4, have a lower freezing point? Explain your reasoning and prove it with calculations. Kf for water is 1.86 °C/m. ΔTf Give a definition of colligative properties. Draw a phase diagram of a pure substance, and show how addition of a solute affects this diagram.
