Question

what is redox reaction in simple language

Answer 1

REDOX REACTION:
The reactions which involves both oxidation and reduction reactions.

reduction — red
oxidation — ox

Its REDOX reaction.

Answer 2

Reduction Redox is a Chemical reaction in which the oxidation states of atoms are changed. Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes.Redox reactions include all chemical reactions in which atoms have their oxidation state changed; in general, redox reactions involve the transfer of electron between chemical species. The chemical species from which the electron is stripped is said to have been oxidized, while the chemical species to which the electron is added is said to have been reduced. It can be explained in simple terms:

Oxidation is the loss of electron or an increase in oxidation state by a molecule, atom, or ion

Reduction is the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion.
When the both oxidation and reduction processes are involved then the reaction is called Redox reaction.
