Notation => [Oxidation Rxn||Reduction Rxn]
[Pt(s) | H₂(g) | H⁺(aq) || SO₄ˉ²(aq) | PbSO₄(s) | Pb(s)]
H₂(g) + Pt(s) => 2H⁺(aq) + 2eˉ (Oxidation Half Rxn)
PbSO₄(s) + 2eˉ => Pb⁰(s) + SO₄ˉ²(aq) (Reduction Half Rxn)
…………………………………………………………..………..
H₂(g) + PbSO₄(s) + Pt(s)* => Pb⁰(s) + SO₄ˉ²(aq) + 2H⁺(aq)
*Pt(s) => Catalyst
