(Tennant investigated this residue and from it he inevitably isolated osmium and iridium.) Wollaston concentrated on the answer of dissolved platinum which also contained palladium. He eliminated these metals by precipitation and was remaining with a good looking red Remedy from which he obtained rose pink crystals. These had been sodium rhodium chloride, Na3RhCl6. From them he inevitably generated a sample from the metal alone. Glossary
