Balancing Redox Reactions: Examples - Chemistry LibreTexts
Jun 12, 2019Practice Problems Oxidation-Reduction or "redox" reactions occur when elements in a chemical reaction gain or lose electrons, causing an increase or decrease in oxidation numbers. The Half Equation Method is used to balance these reactions. In a redox reaction, one or more element becomes oxidized, and one or more element becomes reduced.
