Hot aqua regia will dissolve rhodium only slightly, but will dissolve the others. precipitate the palladium (and trace silver) with sodium bromide. Filter it and dissolve up the palladium in sulfite and go from there, or just add HCl and an oxidant (not too much, you don't want to dissolve the silver chloride in excess HCl), heat, filter, and then go about it the usual way. Ten-karat gold is marked 10k, 16, 417, or 10KP; 14-karat gold is marked 583, 585, or 14KP; 18-karat gold is marked 750 or 18KP; 22-karat gold is marked 916 or 917; and pure gold, 24 karat, is marked 999. Marked platinum will say 900 Plat, Plat 900, Pt900, or 900Pt. Modern palladium is usually marked Pd950. Thus, the metal and its alloys serve as substitutes for platinum in jewelry and in electrical contacts; the beaten leaf is used for decorative purposes. Relatively small amounts of palladium alloyed with gold yield the best white gold. Palladium is used also in dental alloys. The chief use of palladium, however, The best prices for gold and silver are those that are most reliable. Monex gold and silver prices have been an industry respected reference for decades, with over $55 billion in actual customer physical metal transactions. Over time, gold and silver prices tend to move in concert, mostly in opposition of depreciating fiat currencies. Palladium has been used as a precious metal in jewelry since 1939 as an alternative to platinum in the alloys called "white gold", where the naturally white color of palladium does not require rhodium plating. Palladium is much less dense than platinum. Similar to gold, palladium can be beaten into leaf as thin as 100 nm ( 1 ⁄ 250,000 in).
