Question

Complete the following precipitation reaction with balanced molecular, total ionic, and net ionic equations. Remember to include the proper physical states and charges of ions. When writing ions, if a charge number is not "1", place the charge number before the charge sign. If a charge number is "1", do not include the charge number in the formula. Na2S(aq) + ZnSO4(aq) →

Answer 1

Molecular equation (includes all species in the molecular form)

Na₂S(aq) + ZnSO₄(aq) → Na₂SO₄(aq) + ZnS(s)

Total ionic equation (includes all ions. Insoluble solids do not dissociate)

2 Na⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + SO₄²⁻(aq) → 2 Na⁺(aq) + SO₄²⁻(aq) + ZnS(s)

Net ionic equation (includes only ions that participate in the reaction, that is, it does not include spectator ions)

S²⁻(aq) + Zn²⁺(aq) → ZnS(s)
