They possess high positive reduction potentials (e.g.,
The chemistry of precious metals—primarily the (platinum, palladium, rhodium, ruthenium, iridium, and osmium) along with gold and silver —is defined by their remarkable resistance to corrosion, high density, and unique electronic configurations.
Below is an overview of the fundamental chemical principles that govern these elements. 1. Electronic Structure and Relativistic Effects
Most are insoluble in standard acids. Gold and platinum require Aqua Regia (a 3:1 mixture of HClcap H cap C l HNO3cap H cap N cap O sub 3 HNO3cap H cap N cap O sub 3 acts as an oxidant, while the Cl−cap C l raised to the negative power
The most significant chemical application of precious metals is in .
Precious metals form stable bonds with carbon, leading to critical catalysts like the Grubbs' catalyst (Ruthenium) for olefin metathesis or Wilkinson’s catalyst (Rhodium) for hydrogenation. 4. Oxidation States and Geometry
