Which of the following aqueous solutions has the highest osmotic pressure at 25°C? A)0.2 M KBr B)0.2 M ethanol C)0.2 M Na₂SO₄ D)0.2 M KCl

Question

Quizplus · Accepted Answer

Osmotic pressure depends on the number of particles in solution. Na₂SO₄ dissociates into 3 ions (2 Na⁺ and 1 SO₄²⁻), resulting in the highest number of particles and thus the highest osmotic pressure among the given options.
