To use freezing-point depression or boiling-point elevation to determine the molal concentration of a solution. The freezing point, Tf, of a solution is lower than the freezing point of the pure solvent. The difference in freezing point is called the freezing-point depression, ΔTf: ΔTf=Tf(solvent)−Tf(solution) The boiling point, Tb, of a solution is higher than the boiling point of the pure solvent. The difference in boiling point is called the boiling-point elevation, ΔTb: ΔTb=Tb(solution)−Tb(solvent) The molal concentration of the solution, m,...
