Redox (short for reduction–oxidation reaction) is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the transfer of electrons between chemical species, most often with one species (the reducing agent) undergoing oxidation (losing electrons) while another species (the oxidizing agent) undergoes reduction (gains electrons). The chemical species from which the electron is stripped is said to have been oxidized, while the chemical species to which the electron is added is said to have been reduced. In other words:
Oxidation is the loss of electrons or an increase in the oxidation state of an atom by a molecule, an ion, or another atom.
Reduction is the gain of electrons or a decrease in the oxidation state of an atom by a molecule, an ion, or another atom.
