Abstract
The formation of insoluble compounds on zinc in 0.15 M H2SO4 was shown by X-ray photoelectron spectroscopy to be possible. Anodic current-vo ltage curves were obtained for three kinds of zinc surface: polycrysta lline with a mechanically worked surface, electrochemically deposited, and the (0001) single-crystal basal plane. The experimental data obta ined were well described by a model of two-step charge transfer with s urface diffusion of ions of intermediate valency.
