Definitions from the WebRedoxDefinition:Redox, short for reduction-oxidation, refers to a chemical reaction in which there is a transfer of electrons between two species. It involves the simultaneous occurrence of a reduction reaction (gain of electrons) and an oxidation reaction (loss of electrons). Common Uses:1. In Chemistry: - Redox reactions play a crucial role in various chemical processes, such as the generation of energy in batteries and fuel cells. - They are also involved in corrosion, combustion, and the decomposition of organic compounds. - Redox indicators are utilized to determine the endpoint of a titration or to identify the presence of a specific substance in a solution. 2. In Biology: - Redox reactions are fundamental in biological systems, particularly in cellular respiration and photosynthesis. - They facilitate the transfer of electrons during metabolic reactions, enabling the production of ATP (adenosine triphosphate), the energy currency of cells. - Oxidative stress, resulting from an imbalance in redox reactions, is implicated in various diseases and aging processes. Examples:1. Chemistry: - In the process of rusting, iron undergoes a redox reaction with oxygen, resulting in the formation of iron(III) oxide (rust). - The redox reaction occurring in a voltaic cell produces electrical energy by the transfer of electrons between the anode and the cathode. - The redox indicator potassium permanganate (KMnO4) changes color from purple to colorless in the presence of reducing agents. 2. Biology: - During cellular respiration, glucose is oxidized to carbon dioxide, while oxygen is reduced to water. - In photosynthesis, plants undergo a redox reaction by utilizing sunlight energy to convert carbon dioxide into glucose, while releasing oxygen as a byproduct. - Antioxidants, such as vitamin C and vitamin E, help neutralize harmful free radicals in the body by undergoing redox reactions.
