Oxygen and sulfur have a high affinity in chemical reactions with each other. These two elements form a large number of compounds when they react. Sulfur forms many oxyacids that dissociate into their oxyanions in solutions. One of the many sulfur oxyanions is the bisulfite anion. Write a chemical formula for this oxyanion.

• A. HSO₄^-
• B. HSO₃^-
• C. S₂O₃^2-
• D. SO₄^2-
