Oxidation-reduction (Redox) reactions

Today we learn- what is redox reaction, Examples of it.

Redox (short for reduction–oxidation reaction) is a chemical reaction in which the oxidation states of atoms are changed.

Redox (oxidation-reduction) Reaction:

“Redox” is a portmanteau of the words “reduction” and “oxidation”. As we know that the Oxidation and reduction reactions takes place at the same time. The processes occurs simultaneously. So normally they cannot happen independently of one another. Similar to the acid–base reaction. The word comes from the word Oxidation and Reduction. From Readuction, the part Red and from Oxidation, the part Ox is taken. After that the parts are added to mention the Oxidation-Reduction reaction together.

Oxidation reduction

Oxidation Reaction the Reaction in which the electron(s) is released by a chemical species (Reduction agent) is called Oxidation Reaction (oxidation definition). Reduction Reaction the Reaction in which the electron(s) is released by a chemical species (oxidation agent) is called Reduction Reaction (Reduction definition ).

Then, Redox reaction is the reaction (or oxidation-reduction) reaction is a type of chemical reaction that involves a transfer of electrons between two chemical species.

Exapample of this reaction :
As an example, during the combustion of wood, oxygen from the air is reduced, gaining electrons from carbon which is oxidized. This reaction is faster process. The iron reacts to the oxygen in the air and produce rust. This reaction is a slow process.

2C + O2 = CO(Fire, Faster process)

4 Fe + 3 O2 + 6 H2O = 2 Fe2O3.3H2O (Rust, relatively slower process)

The reaction can occur relatively slowly, as in the case of rust, or more quickly, as in the case of fire.
