Tīmeklis2024. gada 29. dec. · $$\ce{i2 + h2o2 + 2 oh- -> 2 i- + 2 h2o + o2}$$ I feel the reaction is not correct. Since $\ce{H2O2}$ is a moderate/strong oxidizing agent, I don't think it can be oxidized by iodine and the reverse reaction should be true since $\ce{O2}$ is a strong oxidising agent and $\ce{I-}$ is a reducing agent.

2. AJUSTA LAS SIGUIENTES ECUACIONES POR MÉTODO REDOX.
TīmeklisBALANCE DE REACCIONES REDOX. El método del cambio de los números de la oxidación es relativamente sencillo, y es un modo fácil de equilibrar las ecuaciones redox. Se basa en el hecho de que el aumento de los números de la oxidación de los reactantes que han sido oxidados tiene que ser idéntico a la disminución de los … TīmeklisNow all that needs balancing is the charges.
