Of the following, a 0.2 M aqueous solution of __________ will have the highest freezing point. A)(NH₄)₃PO₄ B)Pb(NO₃)₂ C)Na₃PO₄ D)Mg(NO₃)₂ E)NaCl

Question

Quizplus · Accepted Answer

The freezing point depression of a solution is directly proportional to the molality of the solute particles in the solution. Since all the given compounds dissociate completely in water to form ions, the molality of the solution is equal to the molarity of the ionic compound. Among the given options, NaCl has the highest molar mass, which means that it will have the highest number of particles in solution for a given concentration. Therefore, a 0.2 M aqueous solution of NaCl will have the highest freezing point among the given options.

Of the Following, a 0
