Question

Quizplus · Accepted Answer

The freezing point depression is proportional to the van't Hoff factor (i), which is the number of particles the solute dissociates into. (NH4)3PO4 dissociates into 4 ions (3 NH4+ and 1 PO4^3-), giving it the highest van't Hoff factor among the options, resulting in the lowest freezing point.
