Oxidation and Reduction

This article is about Oxidation and Reduction reaction.Before discuss about the blog we should know something about its main point .

Oxidation and Reduction

Points To Remember:

1. The Energy which we get in our body is a result of redox reaction.


2. Reduction and Oxidation reaction takes place simultaneously.Where there is oxidation then equal amount of reduction also takes place.In combine form these are called redox reaction.

Electrolysis is also redox reaction where oxidation takes place at anode and reduction takes place at cathode.

The lose of electron by an atom or molecule or ion is called oxidation and gain of electron is called reduction.

Oxidation nature of an atom is directly proportional to electro nagetivity.

Terms	Change in oxidation Numbers	change in electron
oxidation	Increases	Loss of electron
reduction	Decreases	Gain of electron
Oxidising Agent	Decrease	Accepts electron
Redusing agent	Increase	Donates electrons
substance oxidised	Increase	Loses electron
Substance redused	Decrease	Gains electron
