Showing papers on "Overpotential published in 1970"
TL;DR: In this paper, the potential of the tin anode was measured as a function of current density in 0.1-10 N NaOH solutions at 20-40°C and the results indicated the oxidation of tin to stannous oxide.

TL;DR: In this article, it is shown that surface-diffusion rate control at low η is unsatisfactory and that the current is directly proportional to the square root of the corrected strain; there is complex dependence for the latter.

TL;DR: In this article, a study of the diffusion of electrolytic hydrogen in pure iron was made and the effective charge of the diffusing species was calculated to be + 0.26e, which is in good agreement with the value of +0.25e obtained elsewhere from the studies of electrotransport at elevated temperatures.
Abstract: A study has been made of the diffusion of electrolytic hydrogen in pure iron. Diffusion coefficients determined under the conditions of polarisation increased linearly with overpotential over a narrow overpotential range. This may represent conditions of enhanced chemical diffusion. From the mobility and the intrinsic diffusion constant obtained at very low overpotentials, the effective charge of the diffusing species was calculated to be +0.26e, which is in good agreement with the value of +0.25e obtained elsewhere from the studies of electro-transport at elevated temperatures. The value of the apparent charge, or charge of transport, is compared with other ionic states reported for hydrogen and it is concluded that about half of this charge may correspond to ionic bonding.

TL;DR: The simplifying assumptions most commonly made in the phenomenological treatment of electrode processes with regard to the concept of overpotential are critically examined in this paper, where a general procedure is outlined in order to derive phenomenological relations between current density and potential on the basis of the concepts of diffusion layer and reaction layer.
