In a redox reaction, what is the fate of the species that supplies the electrons?

In a redox reaction, the species that supplies electrons is referred to as the reducing agent. This species undergoes oxidation, which involves the loss of electrons. As a result of this process, its oxidation state increases. Oxidation is defined as the process of losing electrons, and it is the key characteristic of the reducing agent in any redox reaction. Therefore, when we look at the reaction, the species providing the electrons experiences an increase in oxidation state and is identified as being oxidized.

This concept is fundamental in understanding redox reactions, where one species is oxidized while another is reduced. It exemplifies the electron transfer nature of several chemical processes.
