Origin of 'iridium'
The term 'iridium' originates from the Latin word 'iris', meaning rainbow, which refers to the various colors of its salts. The element was discovered in 1803 by the English chemist Smithson Tennant while he was analyzing platinum ore. Tennant isolated iridium by treating the residue with aqua regia, a mixture of hydrochloric and nitric acid. Iridium quickly gained interest due to its extreme hardness and high melting point, making it particularly useful in industrial applications. It was also noted for its exceptional resistance to wear and tarnish. Over the years, iridium's applications expanded in various fields, including electronics, chemical industries, and even space technology, contributing to its reputation as one of the most durable materials in the periodic table.
