Answer:
Ba²⁺(aq) + 2OH⁻(aq) + 2H⁺(aq) + SO₄²⁻(aq) → 2H₂O(l) + BaSO₄(s)
Explanation:
The net ionic equation is a chemical reaction that shows only the chemical species that are involved in the reaction.
A solution of Ba(OH)₂ [Ba²⁺ + 2OH⁻], and H₂SO₄ [2H⁺ + SO₄²⁻] produce H₂O and BaSO₄(s). The reaction is:
Ba²⁺(aq) + 2OH⁻(aq) + 2H⁺(aq) + SO₄²⁻(aq) → 2H₂O(l) + BaSO₄(s)
As you can see, all ions are involved in the reaction and you must write all them.
I hope it helps!
