Question

Consider the following half-reaction:

PbO₂(s) → Pb²⁺(aq)

Balance the half-reaction in the basic solution.

Accepted Answer

PbO₂(s) + 2 H₂O(l) + 2 e⁻ → Pb²⁺(aq) + 4 OH⁻(aq)

Answer

PbO₂(s) + 4 H⁺(aq) + 2 e⁻ → Pb²⁺(aq) + 2 H₂O(l)

Answer

Pb²⁺(aq) + 4 OH⁻(aq) → PbO₂(s) + 2 H₂O(l) + 2 e⁻

Answer

PbO₂(s) + 4 OH⁻(aq) + 2 e⁻ → Pb²⁺(aq) + 2 H₂O(l)
