Definitions of oxidation and reduction (redox) - chemguide

Webreduction: a decrease in the number of oxidation of a chemical species, generally due to an acquisition of electrons by the species. Reduction: oxidizing species + n e- → reduced species. Oxidation: reducing species → oxidized species + n e-. being n the number (or moles) of electrons exchanged during the reaction, equal in both half-reactions. WebAn 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). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. shop n save ludington ad
