A 0.100 m solution of which one of the following solutes will have the lowest vapor pressure? A)KClO₄ B)Ca(ClO₄)₂ C)Al(ClO₄)₃ D)sucrose E)NaCl

Question

Quizplus · Accepted Answer

The vapor pressure lowering is directly related to the number of particles in solution. Al(ClO₄)₃ dissociates into four ions (one Al³⁺ and three ClO₄^-), resulting in the highest number of particles and thus the lowest vapor pressure.
