Electrodeposition Behavior of Traces of Silver

Abstract

Previous work has shown a sharp discontinuity between the behavior of the silver deposited on platinum in "trace" and in "macro" amounts. By starting with a solution containing a "trace" of silver and making stepwise additions of known amounts of silver followed each time by a deposition curve, the behavior of intermediate amounts was elucidated. A series of curves was obtained for platinum, palladium, and gold electrodes in various media. These curves were not simple S‐shaped curves, but instead had one or more plateaus in regions of potential more noble than the potential at which complete deposition was obtained.
