Final answer:
The balanced net ionic equation for the reaction between Ba(NO₃)2(aq) and K₂SO₄(aq) is Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s), where Ba²⁺ and SO₄²⁻ combine to form a precipitate of barium sulfate (BaSO₄).
Step-by-step explanation:
To write the balanced net ionic equation for the reaction between Ba(NO₃)2(aq) and K₂SO₄(aq), we need to consider only the ions that participate in forming the precipitate. The full ionic equation for the reaction is:
Ba²⁺(aq) + 2NO₃⁻(aq) + 2K⁺(aq) + SO₄²⁻(aq) → BaSO₄(s) + 2NO₃⁻(aq) + 2K⁺(aq)
The balanced net ionic equation for the reaction:
Ba(NO₃)₂(aq) + K₂SO₄(aq) → BaSO₄(s) + 2KNO₃(aq)
The potassium (K⁺) and nitrate (NO₃⁻) ions are spectator ions and do not participate in the reaction, so they can be omitted from the net ionic equation. The net ionic equation includes only the ions that form the insoluble product, barium sulfate (BaSO₄), which is a precipitate. Thus, the balanced net ionic equation is:
Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)
