All the reactions mentioned in the sections on the front is the ion incorporation reaction, whereby the oxidation number of species-species that reacts is not changed. But there are a number of reactions in which oxidation state changes are accompanied by electron exchange between the reactants.

The process is electrochemical Redox reaction (reduction-oxidation), in which this reaction the energy released by the spontaneous reaction turned into electricity or where electricity is used so that the reaction could non-spontaneously occur. Which one is the reduction oxidation reduction and oxidation is the opposite of the increase in oxidation number.

The term oxidation proved or applied to the process of taking oxygen from a substance or substances. Reduction of itself regarded as a process where oxygen is taken from a substance, then the arrest is also called the reduction of hydrogen so that hydrogen loss should also be referred to as oxidation.
