When oxidation and reduction takes place simultaneously, the reaction is called redox reaction.
Oxidation: losing of electrons Reduction: gaining of electrons
Redox Reaction = Reduction + oxidation
CuO + H2→ Cu + H2O
i. In the reaction, CuO loses oxygen atom which means that reduction of CuO(copper oxide) takes place.
ii. H2 (hydrogen) takes up oxygen atom.
iii. As a result, formation of water takes place. This means hydrogen undergoes oxidation.
iv. Oxidation and reduction are taking place at the same time, thus it a redox reaction.
