Which of the following solutes,dissolved in 1.0 kg of water,creates a solution that boils at the highest temperature? A)0.010 mol H₃PO₄ B)0.010 mol HClO₄ C)0.010 mol H₂SO₄ D)0.010 mol HCl E)0.010 mol HF

Question

Quizplus · Accepted Answer

The boiling point elevation of a solution is directly proportional to the molality of the solute. Out of all the options, H₂SO₄ has the highest number of solute particles after dissociation, i.e. 3 (H+, SO42-, and H₂SO-). This means that it will have the highest molality and, therefore, boiling point elevation.
