Solutions are made that contain 0.1 moles of each of the following compounds below in 100 g of H₂O.Choose the compound whose solution will have the lowest freezing point. A)MgCl₂ B)KClO₃ C)CO₂ D)MgSO₄ E)NaBr

Question

Quizplus · Accepted Answer

The freezing point depression is determined by the van't Hoff factor (i), which is the number of particles the compound dissociates into in solution. MgCl₂ dissociates into 3 ions (1 Mg²⁺ and 2 Cl⁻), which is the highest among the given options, leading to the greatest freezing point depression.
