A 0.200 m solution of which one of the following solutes will have the lowest vapor pressure? A)LiCl B)AlCl₃ C)CaCl₂ D)glucose E)KCl

Question

Quizplus · Accepted Answer

The vapor pressure lowering is directly related to the number of particles the solute dissociates into in solution. AlCl3 dissociates into four ions (Al^3+ and 3 Cl^-), which is the highest among the given options, leading to the greatest reduction in vapor pressure.
