Oxidation involves the loss of electrons or gain of oxygen by an atom or molecule, while reduction is the gain of electrons or loss of oxygen. Redox reactions involve the transfer of electrons between oxidizing agents that gain electrons and reducing agents that lose electrons, with oxidation occurring at one molecule and reduction at the other. Redox reactions are chemical reactions where oxidation and reduction processes simultaneously occur through electron transfer between two reacting species.

1. Redox reactions

2. Oxidation and Reduction
Oxidation is the loss of electrons or an increase
in oxidation state by a molecule, atom, or ion. It is the
gain of oxygen. Reduction is the gain of electrons or a
decrease in oxidation state by a molecule, atom, or ion. It is
the loss of oxygen.

3. Agents
Oxidizing agents
An oxidizing agent oxidizes
other substances and gains
electrons therefore its
oxidation state decreases.
Reducing agents
A Reducing agent reduces
other substances and loses
electrons therefore its
oxidation state increases.

4. Redox Reactions
An oxidation-reduction (Redox) reaction is a type of
chemical reaction that involves a transfer of electrons
between two species.
In REDOX reactions two processes are involved. They are:-
Oxidation
Reduction
