Question

Which of the following is an example of redox reaction?

• A. Burning of fuel
• B. Corrosion of metal
• C. Manufacture of NaOH
• D. Respiration Reaction

Answer 1

Answer: (A), (B), (C)

The correct options are
A

Burning of fuel

B

Corrosion of metal

C

Manufacture of NaOH

Redox reaction include all chemical reaction in which oxidation state change atoms,

in general, redox reaction involving the transfer of electrons between species.

Redox $⟶$ Red +ox $⟶$ Reduction+oxidation

It is a reduction -- oxidation reaction.

All of the examples given in question include reduction or oxidation or both.

Therefore, they all are redox reactions.

So,(a),(b),(c) are correct.
