Boiling Point ElevationThe boiling point of a solution INCREASES with the number of dissolved solute particles. This is summarized by the expression: Tb = m i KbWhere: Tb is the increase in the boiling point = Tb(solution) - Tb(pure solvent) m is the molality of the solution = (# moles solute / kg solvent) i is the "van't Hoff" factor = (# moles of solute particles / mole of solute) For nonelectrolytes: i = 1 For strong electrolytes: i = number of (cations + anions) For weak electrolytes: 1 < i < number of (cations + anions) Kb is the boiling point elevation constant. It depends only on the SOLVENT. Example:Na2SO4 is a soluble salt. It breaks into two Na+ cations and one SO42- anion in solution.i = 2 + 1 = 3 CH3COOH is a weak acid. It breaks into a few CH3COO - anions and a few H+ cations. 1 < i < 2.
