Which of the following pairs of solutions have roughly the same boiling point elevation? A)0)100 m C₆H₁₂O₆ and 0.0333 m CuCl₂ B)0)100 m NaCl and 0.100 m C₆H₁₂O₆ C)0)200 m NaCl and 0.300 m Na₂SO₄ D)0)100 m KCl and 0.0500 m MgBr₂

Question

Quizplus · Accepted Answer

The boiling point elevation depends on the molality of the solution and the number of particles the solute dissociates into. C6H12O6 does not dissociate, while CuCl2 dissociates into 3 ions. Therefore, 0.100 m C6H12O6 and 0.0333 m CuCl2 have similar boiling point elevations because they result in a similar number of solute particles.
