#### Solution Preview

In short, the "freezing point depression" (where freezing point depression = how much lower the freezing point for the solution is, compared to the freezing point of pure solvent (water in this case)) for the FeCl3 solution will be greater than for the NaCl solution. (So, the freezing temperatures will ...
