Which of the following liquids will have the lowest freezing point? A)pure H₂O B)aqueous glucose (0.60 m) C)aqueous sucrose (0.60 m) D)aqueous FeI₃ (0.24 m) E)aqueous KF (0.50 m)

Question

Quizplus · Accepted Answer

Aqueous KF (0.50 m) will have the lowest freezing point because it is a strong electrolyte and will dissociate into K+ and F- ions, which will increase the number of particles in the solution and lower its freezing point according to the colligative property formula. In contrast, the other options are either non-electrolytes or weak electrolytes that will not lower the freezing point as much.
