Which of the following liquids will have the lowest freezing point? A)pure H₂O B)aqueous glucose (0.050 m) C)aqueous CoI₂ (0.030 m) D)aqueous FeI₃ (0.030 m) E)aqueous NaI (0.030 m)

Question

Quizplus · Accepted Answer

The freezing point depression of a solution is directly proportional to the molal concentration of the solute particles. Fe(NO3)3 (choice D) dissociates into four particles (one Fe3+ and three NO3-), which is more than any of the other solutes listed, leading to the lowest freezing point among the options given.
