Abstract
Abstract The a.c. wave of bromide consists of two distinct portions, one, at more negative potentials, arising from the adsorption of bromide ion and the other resulting from the electron transfer process involved in the formation of mercurous bromide. Diffusion-control of adsorption of bromide ion can be detected at low concentrations. Evidence obtained from the shape of the a.c. wave and from current-time curves, both a.c. and d.c., for individual drops suggests that the faradaic process is reversible only over a narrow potential range corresponding to the formation of a mono-layer of mercurous bromide. Bromide ion gives a d.c. pre-step of origin similar to that of chloride.
