Consider the reaction when aqueous solutions of barium bromi

Consider the reaction when aqueous solutions of barium bromide and ammonium sulfate are combined.

The net ionic equation for this reaction is:

Solution

BaBr₂(aq) + (NH₄)₂SO₄ (aq) = 2NH₄Br (aq) + BaSO₄ (s)

Ba²⁺ (aq) + 2Br^- (aq) + 2NH₄⁺(aq) + SO₄²⁺(aq) = 2NH₄⁺(aq) + 2Br^- (aq) + BaSO₄ (s)

Ba²⁺ (aq) + SO₄²⁺(aq) =  BaSO₄ (s)
