For a 0.05 M H₂SO₃ solution,which of the following relationships is true? A)[SO₃^2-] > [H₂SO₃] B)[SO₃^2-] > [HSO₃^-] C)[HSO₃^-] > [H₂SO₃] D)[H₂SO₃] > [H⁺] E)[H⁺] > [H₂SO₃]

Quizplus · Accepted Answer

EThe correct answers are based on the principle of chemical equilibrium and the dissociation of weak acids in solution. For a weak acid like HS^-, it partially dissociates in solution into H^+ and S^2-. Therefore, the concentration of the undissociated acid ([HS^-]) will be greater than the concentration of its dissociated form ([H^+] and [S^2-]), making options D and E correct.
