About the Redox Equation Balancer
A free tool for balancing redox equations by atoms and charge.
What it is
This calculator balances redox equations by solving a linear system that treats every element and the net ionic charge as constraints that must match on both sides. Write species with their ionic charge (like Fe^2+ or MnO4^-), include H^+/OH^-/H2O for acidic or basic media, and the calculator finds the smallest whole-number coefficients.
Features
Atoms and charge together
Balances the full equation, not just atoms.
Acidic or basic media
Works with Hโบ, OHโป, and HโO as explicit species.
Verification table
Confirms every element and charge match after balancing.
