Redox 

A redox reaction is a reaction that involves both oxidation and reduction.

Oxidation: loss of electrons, increase in oxidation number.

Reduction: gain of electrons, decrease in oxidation number.

A redox reaction will always involve a reducing agent and an oxidising agent.

Oxidising agent: takes electrons from a species that is oxidised- is reduced.

Reduicng agent: adds electrons to a species - is oxidised.
