Balancing Redox in Basic Solution

Balancing Redox in Basic Solution

Oxidation Method Steps

• separate into 1/2 reactions

• balance redox element

• find oxidation states

• add the number of transferred electrons

• balance charge on each side by adding OH-

• balancing water and solve normally

1/2 reaction method

• write half reactions

• balance the redox element

• Balance O with water

• Add H+

• add half reactions back together

• add #OH to both sides that will make #H to water

• cancel any duplication of water on each side

Multiple Select

MnO₄^- + SO₃^2- = MnO₂ + SO₄^2-

What is the final balanced equation?

• 2MnO₄^- + 3SO₃^2- + H₂O → 2MnO₂ + 3SO₄^2- + 2OH^-
