Question

Complete and balance the molecular equation for the reaction of aqueous sodium sulfate, Na2SO4, and aqueous barium nitrate, Ba(NO3)2. Include physical states. Enter the Balanced net ionic equation for this reaction.

Answer 1

SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)

Explanation:

molecular equation:

Na₂SO₄ + Ba(NO₃)₂ → BaSO₄ + 2 NaNO₃

Ionic equation:

2 Na⁺ (aq) + SO₄²⁻ (aq) + Ba²⁺ (aq) + 2 NO₃⁻ (aq) → BaSO₄ (s) + 2 Na⁺ (aq) + 2 NO₃⁻ (aq)

We remove the spectator ions to get the balanced net ionic equation:

SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)

were:

(aq) - aqueous state

(s) - solid
