About rhodium

Not merely is rhodium harder than gold, nevertheless it’s also tougher than silver, so rhodium-plating silver provides a layer of protection from scratches. Rhodium is usually whiter and brighter than silver, developing a a lot more lustrous visual appeal.

Chemistry in its element is brought to you through the Royal Society of Chemistry and produced by thenakedscientists.com. There is more info along with other episodes of Chemistry in its factor on our Internet site at chemistryworld.org/things.

Rhodium was found in 1803 by William Wollaston. He collaborated with Smithson Tennant within a professional undertaking, Portion of which was to create pure platinum for sale. Step one in the method was to dissolve ordinary platinum in aqua regia (nitric acid + hydrochloric acid). Not all of it went into solution and it left driving a black residue.

Rhodium isn't going to Participate in a acknowledged vital function in biological devices. Organisms Will not demand it for growth or survival. Even so, its compounds, significantly Individuals with natural ligands, are of fascination to biochemists and pharmacologists for their opportunity therapeutic apps.
