Many processes that occur around us are redox reactions. These include combustion, rusting, photosynthesis, respiration and decomposition.
Redox reactions are chemical reactions involving oxidation and reduction occurring simultaneously.
Therefore, redox reaction is also known as oxidation-reduction reaction.
It is interesting to note that oxidation is always accompanied by reduction. Both oxidation and reduction have to occur simultaneously.
Redox reactions can be explained based on:
(a) Loss or gain of oxygen
(b) Loss or gain of hydrogen
(c) Transfer of electrons
(d) Changes in oxidation number
Types of redox reactions
Not all chemical reactions are redox reactions. For example, acid-base reactions and double decomposition reactions (as in the precipitation method) are non-redox reactions.
Four examples of redox reactions are as follows:
(a) Changing of iron(II) ions to iron(III) ions and vice versa
(b) Displacement of metal from its salt solution
(c) Displacement of halogen from its halide solution
(d) Transfer of electrons at a distance
