Redox Reactions

Redox reactions are considered to be the chemical reactions involving both oxidation and reduction processes. They are actually oxidation-reduction reactions. The term redox is made from two words where “red” comes from reduction and “ox” comes from oxidation. During a redox reaction electron transfer takes place in such a way that one chemical compound gets reduced and the other one gets oxidized.
