Solution

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.

Another name for these type of reaction --redox reaction

The oxidation state(oxydation no) (OS) of an element corresponds to the number of electrons, e^-, that an atom loses, gains, or appears to use when joining with other atoms in compounds. In determining the oxidation state of an atom, there are seven guidelines to follow:

The oxidation state of an individual atom is 0.

The total oxidation state of all atoms in: a neutral species is 0 and in an ion is equal to the ion charge.

Group 1 metals have an oxidation state of +1 and Group 2 an oxidation state of +2

The oxidation state of fluorine is -1 in compounds

Hydrogen generally has an oxidation state of +1 in compounds

Oxygen generally has an oxidation state of -2 in compounds

In binary metal compounds, Group 17 elements have an oxidation state of -1, Group 16 elements of -2, and Group 15 elements of -3.

example for redox reaction

Fe(s)+O2(g)→Fe2O3(g)

Fe and O₂ are free elements; therefore, they each have an oxidation state of 0 according to Rule #1. The product has a total oxidation state equal to 0, and following Rule #6, O has an oxidation state of -2, which means Fe has an oxidation state of +3

So oxidation state of Fe and O changes ,So this is an redox reaction,
