Answer is: spectator ions are NO₃⁻(aq) + 2K⁺.
Balanced reaction hemical reaction:
Ba(NO₃)₂(aq)
+ K₂SO₄(aq) → BaSO₄(s) + 2KNO₃(aq).
Ionic reaction:
Ba²⁺(aq)
+ 2NO₃⁻(aq) + 2K⁺(aq) + SO₄²⁻(aq) → BaSO₄(s) + 2K⁺(aq) + 2NO₃⁻(aq). Net ionic reaction: Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s). A spectator
ion is
an ion that exists as a reactant and a product in a chemical equation.
