If there are no changes in the oxidation state of the reactants or products of a particular reaction, it means that

It is not a redox reaction.

Explanation:

A redox reaction is a type of reaction in which there is a transfer of electrons between species. The species that gains electrons are the oxidant agent since it will be reduced when it takes the electron of the other species, and vice versa, the specie that loses electrons will be the reductant agent since it will be oxidated when it loses its electron.    

Hence in a redox reaction will occur an electron transfer with the following change in the oxidation number between the reactants and the products.

Therefore, If there are no changes in the oxidation state of the reactants or products of a particular reaction, it means that the reaction is not a redox reaction.

Explanation:

REDOX REACTION:

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, ion changes by gaining or losing an electron. Redox reactions are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting. All redox reactions involve changes in the oxidation state of the reactants or products of a particular reaction.
