Answer:
2. precipitate is formed
Explanation:
In this reaction barium nitrate and sodium sulfate solutions react to form a barium sulfate precipitate.Barium and sulfate ions will react to give barium sulfate precipitate where as the sodium and nitrate ions are spectator ions.
The net ionic equation after removing unchanged ions from each side of the full ionic equation will be;
Ba²⁺+ SO₄²⁻ → BaSO₄ (s)
