It involves the transfer of electrons between reactants, leading to a change in oxidation states. Redox or oxidation-reduction reactions are essential in many natural processes and industrial applications. We will discuss the basics of redox reactions, definitions, examples, and applications.The electron loss and gain is easy to see in a reaction in which ions are formed. However, in many reactions, no such electron transfer occurs. In a molecular compound, electrons are shared between atoms in a type of bond called a covalent bond. Yet, it is still common for reactions involving molecular compounds to be classified as redox reactions.Oxidation is an increase in oxidation number (loss of electrons); reduction is a decrease in oxidation number (gain of electrons). 4.7: Oxidation-Reduction Reactions is shared under a not declared license and was authored, remixed, and/or curated by LibreTexts.
