Define ‘redox reaction’. Give one example.

What is redox reaction? Explain with one example

Solution 1

When oxidation and reduction occur simultaneously in a given chemical reaction, it is known as a redox reaction.
Example of a redox reaction:

Reduction         Oxidation

BaSO4 +4C →  BaS+4CO

Solution 2

The reaction in which simultaneous oxidation and reduction take place is called a redox reaction

Cu+2 + Zn → Zn+2 + Cu

in the above reaction, copper undergoes reduction whereas Zn undergoes oxidation.
Therefore the reaction is redox reaction.

Solution 3

The reaction in which one substance gets oxidised and other gets reduced is known as redox reaction.

Example:

ZnO + C → Zn + CO

Here, C is oxidised to CO because oxygen is being added and ZnO is reduced to Zn because oxygen is being removed. Therefore, it is a redox reaction.

 

  Is there an error in this question or solution?
