Définition Palladium
Palladium is more reactive than the other platinum metals. For example, it is attacked more readily by acids than any of the other platinum metals. It dissolves slowly in nitric acid to give palladium(II) nitrate, Pd(NO 3) 2, and with concentrated sulfuric acid it yields palladium(II) sulfate, PdSO 4 ∙2H 2 O. In its sponge form it will dissolve even in hydrochloric acid in the presence of.

Pd In Periodic Table Palladium Pd (Element 46) of Periodic Table
Palladium, ruthenium, rhodium, osmium, indium, and platinum make up the platinum group of metals. These metals are also sometimes called the noble metals. That term reflects the fact that the six elements are not very reactive. Palladium was discovered along with rhodium in 1803 by English chemist William Hyde Wollaston (1766-1828).
