The reaction in which both oxidation and reduction takes place

Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.

A chemical reaction in which both oxidation and reduction takes place simultaneously is called redox. Red=reduction + ox= oxidation
Reaction in which reduction and oxidation both takes place is called redox reaction .
