Gold-silver alloys dissolve completely in mixtures of hydrochloric and nitric acids acids containing potassium chloride in high concentration. In an analytical procedure based on this observation, silver is separated and determined as the chloride, and gold as the metal after reduction with sulfite. Analyses of test alloys, synthetic mixtures, and ancient objects showed that this new procedure is practicable and that results of satisfactory accuracy can be obtained.
