Abstract
The properties of the metal‐solution potentials of nickel in nickel free hydroxide and phosphate solutions are compared with the properties of unpolarizable electrodes and with the properties of polarizable metal‐solution systems. The electrochemical equilibria of unpolarizable systems are analyzed in terms of transfer mechanisms between the phases present. In the absence of any electrochemical equilibria, the metal‐solution potentials are interpreted as adsorption potentials. Chemisorption in the inner Helmholtz layer is discussed in connection with ``reversibility'' and polarizability of the system.Keywords
