Colligative Properties Worksheet The amount of the elevation of the boiling point of a solution is given by Δ Tb = ik b m where k b is the molal boiling point elevation constant of the solvent and m is the molal concentration of the solute. The amount of the depression of freezing point is given by Δ Tf = -ik f m where k f is the molal freezing point depression constant of the solvent and m is the molal concentration of the solute. When working with ionic solutes in water and other polar solvents, one must be careful to take into consideration the fact that the ion concentration is higher than the concentration of the solute. For example, table salt, NaCl dissolves in water to form ions NaCl(s) -> Na+(aq) + Cl-(aq). Each mole of NaCl makes two moles of ions, so if we have a 1 molal solution of NaCl in water, the ion concentration is 2 molal. Remember, nonelectrolyte solutes do not produce any ions. 1.
