Question

Define oxidation and reduction by giving an example of each

Answer 1

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
Most of the time, oxidation occurs in tandem with a process called reduction. ... In an oxidation-reduction, or redox, reaction, one atom or compound will steal electrons from another atom or compound
. A classic example of a redox reaction is rusting. When rusting happens, oxygen steals electrons from iron.

Bonjour!

$Oxidation:$ Addition of Oxygen or removal of Hydrogen.
Eg:- 2Cu + O2 –––» 2CuO

$Reduction:$ Removal of Oxygen and addition of Hydrogen.
Eg:- 2H2O ––electrolysis––» 2H2 + O2
