Question

what is Redox reaction . explain with example

Answer 1

Redox reaction is a chemical reaction in which the oxidation states of atoms are changed.
Eg:-A good example is the reaction between hydrogen and fluorine in which hydrogen is being oxidized and fluorine is being reduced:

H
2 + F
2 → 2 HF

Answer 2

Those reactions in which oxidation and reduction takes place simultaneously, are called redox reactions.

e.g.

In the following reaction, the copper (II) oxide is losing oxygen and is being reduced. Whereas, oxygen is added to hydrogen and is being oxidized.
