Question

Define ‘redox reaction’. Give one example.

What is redox reaction? Explain with one example

Answer 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

Answer 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.

Answer 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.
