Volta Potential

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Volta potential (also called Volta potential difference, or contact potential difference, or outer potential difference, , delta psi) in electrochemistry, is the electric potential difference between two points in the vacuum: close to the surface of metal M1 close to the surface of metal M2, where M1 and M2 are two uncharged metals brought into contact.The Volta potential is named after Alessandro Volta.When two metals are electrically isolated from each other, an arbitrary potential difference may exist between them. However, when two different metals are brought into contact, electrons will flow from the metal with a lower work function to the metal with the higher work function until the electrochemical potential of the electrons in the bulk of both phases are equal....
