Previously published methods for the electrolytic determination of silver are not entirely satisfactory. The cyanide procedure gives good results for the determination of silver alone, but is not satisfactory as a separation of silver from copper unless a rather low current density is used6. Also, l
Copper can be separated from tin by elcctrodeposition from a phosphoricnitric acid medium?, or a hydrofluoric-nitric acid medium2\* 4. Such separations, however, have a distinct drawback. Before the tin can be determined on the electrolyte the solution must be fumed with sulfuric acid to drive off t
Recently a method was proposed by the author2 for the electrolytic determination of copper in tin-base alloys. In this method the sample was dissolved in hydrochloric and nitric acids, then phosphoric acid was added and the solution heated on the hot plate about a half hour to drive off the hydrochl
