net ionic equation

Question

Write a net ionic equation for the reaction that occurs when excess nitric acid (aq) and potassium sulfite (aq) are combined. Note: Sulfites follow the same solubility trends as sulfates.

Answer 1

2HNO₃(aq) + K₂SO₃(aq) ==> 2NO₂(g) + H₂O(l) + K₂SO₄(aq) (if HNO3 is concentrated)

NIE: 2H⁺(aq) + 2NO₃^-(aq) + SO₃^2-(aq) => 2NO₂(g) + H₂O(l) + SO₄^2-(aq)
