Question

Balance the following redox reaction under basic conditions and identify the oxidizing and reducing agents:

CrO₂^-(aq) + S₂O₈^2-(aq) → CrO₄²^-(aq) + SO₄^2-(aq)

Accepted Answer

2 CrO₂^-(aq) + 8 OH^-(aq) + 3 S₂O₈^2-(aq) → 2 CrO₄^2-(aq) + 4 H₂O(aq) + 6 SO₄^2-(aq), RA: CrO₂^-(aq) , OA: S₂O₈^2-(aq)

Answer

3 CrO₂^-(aq) + 8 OH^-(aq) + 4 H₂O(aq) + 3 S₂O₈^2-(aq) → 3 CrO₄^2-(aq) + 4 H₂O(aq) + 6 SO₄^2-(aq), RA: S₂O₈^2-(aq) , OA:CrO₂^-(aq)

Answer

3 CrO₂^-(aq) + 8 OH^-(aq) + 3 S₂O₈^2-(aq) → 3 CrO₄^2-(aq) + 4 H₂O(aq) + 6 SO₄^2-(aq), RA: S₂O₈^2-(aq) , OA:CrO₂^-(aq)

Answer

2 CrO₂^-(aq) + 8 OH^-(aq) + 4 H₂O(aq) + 3 S₂O₈^2-(aq) →2 CrO₄^2-(aq) + 4 H₂O(aq) + 6 SO₄^2-(aq), RA: CrO₂^-(aq) , OA: S₂O₈^2-(aq)
