Redox Half-Reaction Balancer

Balance aqueous redox equations by the half-reaction method — oxidation states, split halves, H₂O / H⁺ / e⁻, optional conversion to basic solution, then electron equalization.

Everything you need to balance redox reactions

Half-reaction method

Split the equation into oxidation and reduction halves, balance atoms and charge, then equalize electrons.

Acidic or basic

Balance in acidic medium or convert to basic solution when needed.

Step-by-step output

See oxidation-state changes, balanced halves, and the method steps for each problem.

Net ionic input

Enter net ionic species (for example MnO₄⁻ and Fe²⁺) for classroom and exam-style problems.
