A redox reaction is a reaction in which there is a transfer of electrons from one species to another. In electrochemistry, redox reactions are fundamental as they involve the transfer of electrons, which is central to the generation of electricity and the functioning of electrochemical cells.

Electroplating is the process of producing a metal coating on a solid substrate through the reduction of cations via electrolysis. The substrate to be plated is immersed in a solution containing metal ions, and an electric current is passed through the solution, causing the metal ions to be reduced and deposit onto the substrate as a thin, even layer of metal.

The redox couple in a half reaction consists of the reduced and oxidized species, and it is denoted as Ox/Red. The significance of the redox couple lies in its representation of the electron transfer process, providing a clear understanding of the transfer of electrons during the redox reaction.

<p>The transfer of electrons in redox reactions can be used to do work if the electrons are made to flow through an external device or circuit. This flow of electrons provides energy that can be harnessed to perform useful work.</p> Signup and view all the answers
