Question

Write the balanced net ionic equation, including the phases, for the given reaction. A solution of Ba ( OH ) 2 and a solution of H 2 SO 4 are mixed. Water and a precipitate of BaSO 4 are formed.

Answer 1

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!
