Which of the following aqueous solutions will have the lowest freezing point? A)0.1 m magnesium sulfate, MgSO₄ B)0.1 m potassium chloride, KCl C)0.08 m magnesium chloride, MgCl₂ D)0.04 m sodium sulfate, Na₂SO₄ E)0.05 m sodium chloride, NaCl

Question

Quizplus · Accepted Answer

The freezing point depression depends on the molality and the number of particles the solute dissociates into. MgCl₂ dissociates into 3 ions (Mg²⁺ and 2 Cl⁻), and at 0.08 m, it results in the highest concentration of particles, leading to the lowest freezing point.
