| Abstract: | ![]()
In the Ir(210)/aqueous HCl solution system the “hydrogen adsorption region” is due to the combined process of hydrogen and chloride ion adsorption. We demonstrate that by using impedance spectroscopy the rates of, and charges associated with, hydrogen and chloride adsorption rates can be determined separately. Published in Elektrokhimiya in Russian, 2009, Vol. 45, No. 1, pp. 32–41. Dedicated to the 100th anniversary of B.V. Ershler. The text was submitted by authors in English. |
