Question
Which of the following equimolal ($0.10\text{ m}$) aqueous solutions will have the highest freezing point (closest to $0^\circ\text{C}$)? (Assume equal and complete ionization where applicable).
Answer: A
💡 Solution & Explanation
The highest freezing point corresponds to the *smallest* depression ($\Delta T_f$), which requires the smallest van't Hoff factor ($i$). Glucose is a non-electrolyte ($i=1$), providing the fewest particles and thus the least depression compared to the salts.
