Question

explain redox reactions with examples​

Answer 1

Redox reaction is a reaction where oxidation as well as reduction occurs simultaneously.

Answer 2

The reaction which involves simultaneous oxidation and reduction is called a redox reaction.
example:
CuO+H2---->Cu+ H2O
in this reaction oxygen is removed frim copper oxide therefore it is a reduction ofCuO, while hydrogen accepts oxygen to form water that means oxidation of hydrogen takes place. Thus oxidation and reduction reactions occur simultaneously.
