A 0.020 m aqueous solution containing which solute will have the lowest freezing point?
A)LiCl
B)NaF
C)KCl
D)All will have approximately the same freezing point.

Question

Quizplus · Accepted Answer

The freezing point depression is directly proportional to the molality of the solution. All the given solutes are 1:1 electrolytes, so they will all produce the same number of ions in solution and have the same molality. Therefore, they will all have approximately the same freezing point.
