Redox (reduction-oxidation) reactions involve the transfer of electrons between species. Oxidation is the loss of electrons, while reduction is the gain of electrons. The oxidizing agent accepts electrons, and the reducing agent donates them. Balancing redox reactions requires accounting for electron transfer, often using half-reactions. Example: Zn + Cu²⁺ → Zn²⁺ + Cu. Redox processes are central to metabolism, batteries, corrosion, and industrial chemical production.
