उत्तर
In the electronic concept, oxidation is a process in which an atom or ion loses an electron(s).
Zn → Zn2+ + 2e-
Oxidation is also defined as a chemical process which involves
Addition of oxygen
Addition of electronegative ion
Removal of hydrogen
Removal of electropositive ion (element)
In the electronic concept, reduction is a process in which an atom or ion gains electrons.
Cu2+ + 2e-→ Cu
The reduction is also defined as a chemical process which involves
Removal of oxygen
Addition of electropositive ion
Addition of hydrogen
Removal of electronegative ion
