Lead (II) nitrate reacts with aluminum sulfate in a double displacement precipitation reaction. Which of the following equations is the complete ionic equation?
1) Pb²⁺(aq) + 2NO₃⁻(aq) + 2Al³⁺(aq) + 3SO₄²-(aq) → PbSO₄(s) + 2Al³⁺(aq) + 6NO₃⁻(aq)
2) Pb²⁺(aq) + 2NO₃⁻(aq) + 2Al³⁺(aq) + 3SO₄²-(aq) → PbSO₄(s) + 2Al³⁺(aq) + 3NO₃⁻(aq)
3) Pb²⁺(aq) + 2NO₃⁻(aq) + Al³⁺(aq) + 3SO₄²-(aq) → PbSO₄(s) + Al³⁺(aq) + 3NO₃⁻(aq)
4) Pb²⁺(aq) + 2NO₃⁻(aq) + Al³⁺(aq) + 3SO₄²-(aq) → PbSO₄(s) + Al³⁺(aq) + 6NO₃⁻(aq)
