What is the net ionic equation for the reaction between aqueous BaCl₂ and aqueous Na₂SO₄?
A.Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)
B.Na⁺ + Cl⁻ → NaCl(s)
C.Ba²⁺ + 2Cl⁻ → BaCl₂(s)
D.2Na⁺ + SO₄²⁻ → Na₂SO₄(s)
Explanation
Core Concept
Barium sulfate is insoluble, so Ba²⁺ and SO₄²⁻ combine; Na⁺ and Cl⁻ are spectators. Charges and masses balance as written.
Correct Answer
ABa²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)
