Question

write an equation for the precipitation (if any) that occurs when solution of sodium sulfate (Na2SO4) and barium chloride (BaCl2) are mixed. Write balanced molecular, complete ionic and net ionic equations for the reaction.

Answer 1

Na₂SO₄ + BaCl₂ = BaSO₄ + 2NaCl;
2Na⁺ + SO₄^2- + Ba²⁺ + 2Cl^- = BaSO₄↓+ 2Na⁺ + 2Cl^-
2Na⁺ + SO₄^2- + Ba²⁺ + 2Cl^- = BaSO₄↓+ 2Na⁺ + 2Cl^-
Ba²⁺+ SO₄^2- = BaSO₄↓
