Now that we know what spectator ions are; we must also know they don't appear in the net ionic equation. Which is the correct net ionic equation for the reaction of CaBr2 (aq)+Na₂ SO₄ (aq). A) SO₄²⁻(aq)+Ca2⁺(aq) → CaSO₄ (s) B) Br⁻(aq)+Na⁺(aq) → NaBr(s) C) 2 Br⁻(aq)+Na⁺(aq) → NaBr₂(s) D) Br⁻(aq)+2Na⁺(aq) → Na₂Br(s) E) There is no precipitate that forms.
