·      Oxidation involves the addition of oxygen or the removal of hydrogen

·      Oxidation involves the loss of one or more electrons

·      Reduction involves the removal of oxygen or the addition of hydrogen

·      Reduction, involves the gain of one or more electrons

·      Oxidising Agent (oxidizer) is a chemical compound that readily transfers oxygen atoms or substance that gains electrons in a Redox Reaction.

·      Reducing Agent: Substance that brings about reduction (depletion of oxygen or addition of Hydrogen) in other substance by being itself oxidized in a chemical reaction.

·      The reaction in which oxidation and reduction takes place simultaneously are called Redox reaction

·      Oxidation number of an element indicates the number of electrons lost, gained or shared as a result of chemical bonding.

In oxidation, oxidation number increases

In reduction, oxidation number decreases
