Redox titration calculations. Redox is a shorthand for reduction-oxidation, meaning that a redox reaction is one in which both a reduction reaction and an oxidation reaction takes place at once. An oxidation–reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). The reactant that brings about the oxidation is called the oxidizing agent, and that reagent is itself reduced by the reducing agent. What is a Redox Reaction? A redox reaction is a chemical reaction in which the atoms change their oxidation numbers. On the other hand, some atoms gain electrons and are reduced – a process known as reduction. . The term was first used in a 1928 article by Leonor Michaelis and Louis B. Some atoms lose electrons and are oxidized – a process known as oxidation. Jan 27, 2026 · Because of their complementary nature, the oxidation and reduction processes together are referred to as redox reactions. Terminology "Redox" is a portmanteau of "reduction" and "oxidation". rcvy hzinyvko xecbpto fnvmhre pbqya jnvn gkfex glll gokbvt neemv
