Ba (NO₃) ₂ (aq) + H₂SO₄ (aq) → BaSO₄ (s) + 2HNO₃ (aq)

Explanation:

The equation bellow can be explained by the dissociation of each specie:

Ba (NO₃) ₂ (aq) → Ba²⁺ (aq) + 2NO₃⁻ (aq)

H₂SO₄ (aq) → 2H⁺ (aq) + SO₄²⁻ (aq)

The reaction will lead to the formation of solid barium sulfate and nitric acid.
