We reply to the remarks by Lang and Horanyi [G.G. Lang, G. Horanyi, Electrochim. Acta (2006), doi: 10.1016/j.electacta.2006.07.009] on the meaning of the notion of "electrosorption valency" used by Abou Hamad et al. [I. Abou Hamad, S.J. Mitchell, Th. Wandlowski, P.A. Rikvold, G. Brown, Electrochim. Acta 50 (2005) 5518]. It is concluded that, contrary to the assertion of Lang and Horanyi, the magnitude of the current in the external circuit upon adsorption of an ion of charge ze with partial charge transfer is indeed given by an electrosorption valency gamma such that vertical bar ye vertical bar < vertical bar ze vertical bar. We believe the conclusion of Lang and Horanyi to the contrary is the result of an excessively severe charge-neutrality requirement. (c) 2006 Elsevier B.V. All rights reserved.
