Combining aqueous solutions of BaI₂and Na₂SO₄affords a precipitate of BaSO₄. Which ion(s) is/are spectator ions in the reaction? A) SO₄²^-and I^- B) Ba²⁺only C) Na⁺and I^- D) Na⁺only E) Ba²⁺and SO₄²^-

The spectator ions are those that do not participate in the chemical reaction and remain in their original form. In this case, Ba2+ and I-, which are present in the reactants and products, are not spectator ions as they form the precipitate of BaSO4. Na+, on the other hand, remains in its original form and does not contribute to the formation of the precipitate, making it a spectator ion. Therefore, the correct answer is C, Na+ and I- are spectator ions.
