0Oxidation Reaction: In an oxidation reaction, the addition of oxygen or removal of hydrogen or loss of electron takes place.
eg: 2 Mg(s) + O2(g) → 2Mgo (s)
2 Cu + O2 → 2 CuO (Black)
Reduction Reaction: In reduction Reaction addition of hydrogen or removal of oxygen or gain
of electron takes place.
eg: CuO(s) + H2(g) → Cu(s) + H2O (I)
Redox Reaction: Reaction involving both oxidation and reduction simultaneously.
eg: CuO(s) + H2(g) → Cu(s) + H2O (I)
