Redox reactions, also known as oxidation-reduction reactions, are fundamental processes in chemistry and biology. They involve the transfer of electrons between substances, resulting in changes in their oxidation states. In a redox reaction, one substance is oxidized (loses electrons) while another is reduced (gains electrons). The substance that is oxidized is called the reducing agent, and the substance that is reduced is called the oxidizing agent. Redox reactions are crucial in various natural and industrial processes, including respiration in living organisms, corrosion, and the production of electricity in batteries. The overall reaction can be represented by a redox equation, which shows the electron transfer between the reactants and products. Redox reactions are often coupled, meaning that the oxidation of one substance is accompanied by the reduction of another. This coupling ensures that the total number of electrons lost in oxidation is equal to the total number of electrons gained in reduction, maintaining the conservation of charge. Redox reactions are governed by the principles of thermodynamics and kinetics, and they play a vital role in maintaining the energy balance in biological systems and driving many chemical transformations in industrial settings.
