How do you calculate freezing point depression from a lab?
CONCLUSION. In conclusion, freezing point can be determined when the temperature of liquid and solid are at equilibrium, so that their vapour pressure is equal. The vapour pressure of solution can be lower than pure solvent when a non-volatile solute is added into volatile liquid solvent.What is the conclusion of freezing point depression lab?
Freezing point depression is a colligative property observed in solutions that results from the introduction of solute molecules to a solvent. The freezing points of solutions are all lower than that of the pure solvent and is directly proportional to the molality of the solute.
