Redox reactions are reactions where both oxidation and reduction are taking place.

Displacement reactions are examples of redox reactions as one species is being oxidised (losing electrons) while the other is being reduced (gaining electrons)

Oxidation-Reduction Reaction, also called redox reaction, is any chemical reaction in which the oxidation number of a participating chemical species changes.

When a change in oxidation number occurs in a reaction, with both an increase in number and a decrease in number, then the reaction is classified as redox. If this does not occur, then the reaction is non-redox.


A redox equation can be balanced using the following stepwise procedure:

(1) Divide the equation into two half-reactions.

(2) Balance each half-reaction for mass and charge.

(3) Equalize the number of electrons transferred in each half-reaction.

(4) Add the half-reactions together.
