Detailed explanation-2: -The first two of three following definitions of oxidation are outdated: Oxidation as a gain of oxygen – An oxidizing agent gives oxygen atoms to another substance in a compound. Oxidation as a loss of hydrogen – An oxidizing agent removes hydrogen atoms from another substance in a compound.
Detailed explanation-3: -Oxidative processes are those chemical/biochemical reactions that involve the transfer of 1 or more electrons from an electron donor (reductant) to an electron acceptor (oxidant) leading to the transformation of both the oxidant and the reductant.
Detailed explanation-4: -Iron rusting and wood-rotting are good examples of gradual oxidation.
