Identify the spectator ions in this reaction. Check all that apply.2H+ + CrO4– + Ba2+ + 2OH– Ba2+ + CrO4– + 2H2O

Spectator ions appear unchanged on both sides of the equation. Ba²⁺ and CrO₄⁻ are present as ions on both sides, so they do not take part in the reaction. H⁺ and OH⁻ form water, so they are not spectator ions.
