1. Identify the Ions
* Lead Nitrate:
* Lead (Pb) forms a +2 ion (Pb²⁺).
* Nitrate (NO₃) is a polyatomic ion with a -1 charge (NO₃⁻).
* Copper Sulfate:
* Copper (Cu) can form two common ions: Cu⁺ (cuprous) and Cu²⁺ (cupric). We'll assume the more common Cu²⁺ for this example.
* Sulfate (SO₄) is a polyatomic ion with a -2 charge (SO₄²⁻).
2. Balance the Charges
* Lead Nitrate: To balance the charges, we need two nitrate ions for every lead ion: Pb²⁺ + 2NO₃⁻ → Pb(NO₃)₂
* Copper Sulfate: The charges are already balanced in a 1:1 ratio: Cu²⁺ + SO₄²⁻ → CuSO₄
Therefore, the ionic formulas are:
* Lead Nitrate: Pb(NO₃)₂
* Copper Sulfate: CuSO₄
