A buffer solution was created by combining aqueous solutions of H₂SO₃ and NaHSO₃. Give the balanced chemical equation that illustrates how an added acid will be neutralized in the solution.

• A. HSO₃^–(aq) + H₃O⁺(aq) → H₂SO₃(aq) + H₂O(l)
• B. HSO₃^–(aq) + H₂O(aq) → SO₃^2–(aq) + H₃O⁺(aq)
• C. HSO₃^–(aq) + H₃O⁺(aq) → H₂SO₃(aq) + OH^–(aq)
• D. HSO₃^–(aq) + H₂O⁺(aq) → H₂SO₃(aq) + OH^–(aq)

Answer: (A)
