Answer: Oxidation is a process in which an atom taking part in chemical reaction loses one or more electrons. Te loss of electrons results in the increase of positive charge ( or ) decrease of negative of the species.Example : Mg → Mg2+ + 2e- ( increase of positive charge ) Fe2+ → Fe3+ + e- ( increase of positive charge ) Cu → Cu2+ + 2e- ( increase of positive charge ) S2- → S + 2e- ( decrease of negative charge ) MnO42- → MnO4- + e- ( decrease of negative charge ) Loss of electrons during the reactions are called reducing agents or reductants. In the above equationMg ,Fe2+ , Cu are reducing agents. Some important oxidizing agents are, O2 , O3 , H2O2 , Cl2 , HNO3 , KMnO4 , etc. Hope now confident on Q&A read less
