Answer 2

Hey There!

To know about Redox reactions, we must first know about Oxidation & Reduction... So, Let's get started!

Oxidation : The addition of oxygen or removal of hydrogen in a reaction is called oxidation.

Reduction : The addition of hydrogen or removal of oxygen in a reaction is called reduction.

Now,

Redox Reaction : A reaction in which oxidation & reduction occur together is termed as redox reaction.

Eg :

CuO + H₂ → Cu + H₂O

Substance oxidised → H₂
Substance reduced → CuO
Oxidising agent → CuO
Reducing agent → H₂
