how to test a metal that you suspect of being rhodium, how to test for the presence of rhodium , how to know the metal you think is rhodium.
Rhodium (Rh), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, predominantly used as an alloying agent to harden platinum. Rhodium is a precious, silver-white metal, with a high reflectivity for light. It is not corroded or tarnished by the atmosphere at room temperature and is frequently electroplated onto metal objects and polished to give permanent, attractive surfaces for jewelry and other decorative articles. The metal is also used to produce reflecting surfaces for optical instruments. In
Rhodium added to platinum in small amounts yields alloys that are harder and lose weight at high temperatures even more slowly than pure platinum. Such alloys are used for laboratory furnace crucibles, spark-plug electrodes, and catalysts in very hot chemical environments (including automobile catalytic converters). In the industrial manufacture of nitric acid, gauze catalysts of rhodium–platinum alloys are used because they can withstand the flame temperature as ammonia is burned to nitric oxide. A wire of the alloy 10 percent rhodium–90
