Redox Reactions

A chemical reaction in which oxidation and reduction take place simultaneously is called a redox reaction.

Oxidation: I. The addition of oxygen is called oxidation.

Ex: 2 Mg + O2→ 2 MgO

II. The addition of electronegative elements is oxidation.

Ex: Mg + F2→MgF2

III. The removal of Hydrogen is also oxidation.

Ex: CH4+2O2→CO2+2H2O

IV. The removal of electropositive elements is called oxidation.

Ex: 2 K4[Fe(CN)6]+H2O2→2 K3[Fe(CN)6]+2 KOH

Reduction: I. The removal of oxygen is called reduction.

II. The removal of electronegative elements is reduction.

III. The addition of Hydrogen is also reduction.

IV. The addition of electropositive elements is reduction.
