Who discovered rhodium?
Rhodium was discovered in 1803 by English chemist William Hyde Wollaston. He had earlier discovered the first method for processing platinum ore and it was during this process that he discovered the element rhodium. This occurred after he had removed the platinum and palladium from the crude platinum ore and was left with a dark red powder. This powder contained rhodium chloride salts and he was able to obtain the pure rhodium from this substance by treating it with hydrogen gas. Rhodium was named after the rose color of the rhodium chloride salts and comes from the Greek word “rhodon,” which means rose.

Wollaston also discovered palladium earlier in 1803 while processing platinum ore. Palladium is also considered to be a noble metal.
