Redox Reaction Calculator
Balance oxidation-reduction reactions step by step
About Redox Reactions
Redox Reactions Calculator (reduction–oxidation) reactions involve the transfer of electrons between species. – Oxidation: loss of electrons – Reduction: gain of electrons
Steps to Balance
1. Write oxidation & reduction half-reactions 2. Balance atoms other than O and H 3. Balance O with H₂O, and H with H⁺ 4. Balance charges with e⁻ 5. Multiply half-reactions to equalize e⁻ 6. Add half-reactions together
Worked Example
Reaction: Fe²⁺ + MnO₄⁻ → Fe³⁺ + Mn²⁺ Balanced: 5Fe²⁺ + MnO₄⁻ + 8H⁺ → 5Fe³⁺ + Mn²⁺ + 4H₂O
Applications
– Electrochemistry (batteries, fuel cells) – Corrosion & metallurgy – Environmental chemistry (redox in water/soil) – Biochemistry (cellular respiration, photosynthesis)
