Question

Canvas Classes · Accepted Answer

Strategy:
 Freezing point depression is proportional to the total number of particles in the solution (). Identify the solute with the highest van't Hoff factor ().

Analyzing Solutes:
1. Glycine: Amino acid, behaves as a zwitterion in neutral water; negligible dissociation ().
2. Hydrazine: Weak base; negligible dissociation ().
3. : Salt of a strong base and strong acid anion. In water, it dissociates significantly:  ().
4. Glucose: Non-electrolyte ().

Conclusion:
 provides the most particles
