Lead (II) Nitrate reacts with Aluminum Sulfate in a double displacement precipitation reaction. Which of the following equations is the net ionic equation for the formation of the precipitate?
(a) Pb²⁺(aq) + 3NO₃⁻(aq) + 2Al³⁺(aq) + 3SO₄²⁻(aq) → PbSO₄(s) + 2Al³⁺(aq) + 3NO₃⁻(aq)
(b) 3Pb²⁺(aq) + 6NO₃⁻(aq) + 2Al(s) + 3SO₄²⁻(aq) → 3PbSO₄(s) + 2Al³⁺(aq) + 6NO₃⁻(aq)
(c) Pb²⁺(aq) + SO₄²⁻(aq) → PbSO₄(s)
(d) Al³⁺(aq) + 3 NO₃⁻(aq) → Al(NO₃)₃(aq)
