Oxidation
A substance is associated with oxygen.
A substance is used with a Negative electrical element.
Hydrogen is isolated from a substance.
A positive electrical element is isolated from a substance.
That substance is called oxidation.
Some Examples of Oxidation
C + O2 → CO2
2HgCl2 + SnCl2 → Hg2Cl2 + SnCl4
In this reaction Tin(Sn) is a positive electrical element in SnCl2 and Cl is a Negative electrical element.
4HI + O2 → 2I2 + 2H2O
Reduction
A substance is associated with Hydrogen.
A substance is used with a positive electrical element.
Oxygen is isolated from a substance.
A Negative electrical element is isolated from a substance.
That substance is called Reduction.
Some examples of Reduction:
H2 + Cl2 → 2HCl
CuCl2 + Cu → Cu2Cl2
ZnO + C → CO + Zn
Redox Reactions
If there is the oxidation of a substance in a chemical reaction, then it is also necessary for the reduction of another substance. Similarly, if the reduction of a substance occurs in a chemical reaction, then oxidation of another substance also takes place. Therefore, in a chemical present, oxidation and reduction are carried together.
Example:
In given reaction HgCl2 takes reduction and SnCl2 takes Oxidation.
2HgCl2 + SnCl2 → Hg2Cl2 + SnCl4
Chemical reactions that contain oxidation and reduction are called oxidation-reduction and redox reactions.
