Abstract

The document describes a volumetric method for the determination of silver in jewellery alloys, preferably within the range of fineness stated in ISO 9202. These alloys may contain copper, zinc, cadmium and palladium. Apart from palladium, which must be precipitated before commercing titration, these elements do not interfere with this method of determination.
