Ajuste redox en medio básico | Método ion-electrón paso a paso

In this video, we solve a redox balancing problem using the ion-electron method, step by step, explaining the most common mistakes. You'll see how to: identify which species is oxidized and which is reduced, correctly balance O₂ with H₂O and H₂ with OH⁻, check the final mass and charge, and avoid typical errors when adding the half-reactions. We recommend that you try to solve the exercise before watching the solution and note down any mistakes you make, because in redox, the most important thing is to identify where you're going wrong.
