Explanation:
A redox or oxidation-reduction reaction is a chemical reaction where exchange of electron(s) happen between two chemical species (molecule, atom or ion). In this reaction, one chemical species act as an oxidizing agent while another will be a reducing agent.
An example of redox reaction is given in the attachment.
In a redox reaction, the oxidation number of a reducing agent will be increased, whereas oxidizing agent will be reduced.
