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

Question

Quizplus · Accepted Answer

Adding a solute to a solvent lowers its freezing point. The greater the concentration (molality) of the solute, the greater the depression of the freezing point. KF is an ionic compound that dissociates in water to form K+ and F- ions. As a result, it forms more solute particles in solution than the other compounds given. Therefore, aqueous KF (0.50 m) will have the lowest freezing point.
