If freezing point depression was used to determine the molecular weight of an acid dissolved in water, and the dissociation of the acid wasn't taken into account, the determined value of the molecular weight of the acid would be:

Question

Quizplus · Accepted Answer

The dissociation of the acid in water increases the number of particles in solution, leading to a greater freezing point depression than expected for a non-dissociating substance. If this effect is not accounted for, the calculation would suggest a lower molecular weight than the actual value, because it would seem like more moles of solute were present due to the dissociation.
