Describe two reaction to prove that oxidation and reduction occur simultaneously

Answer»

Answer:

The reactiom which involves similtaneoUs oxidation and reduction is called an oxidation-reduction or redox reaction.

Example:-cuo+H2 ➡cu+H20

In this reaction,oxygen is removed from copper oxide therefore it is a reduction of cuo,while hydrogen accepts oxygen to form water that means oxidation of hydrogen takes place.thus oxidation and reduction reactions occur simultaneously.

Other example of redox reaction:-

2H2s + So2 ➡ 3s + 2H2o

Mno2 +4Hcl ➡ MnCl2 + 2H2O + Cl2⬆
