Derive equation use to calculate depression in freezing point?
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.
where ΔTf is the freezing point depression,
Tf(solution) is the freezing point of the solution,
Tf (solvent) is the freezing point of the solvent,
Kf is the freezing point depression constant,
m is the molality.
