Abstract
A method for electroplating sliver is described which comprises a plating and/or stripping solution of an alkali hydroxide and ethylenediamine having a basic pH in the range of about 7.5 to 13, and having an ethylenediamine concentration of about 5 to 33% by volume, the electroplating (at the cathode) and/or stripping (at the anode) being performed with an applied DC potential across the electrodes of about 2 to 6 volts.
