palladium | Uses, Properties, & Facts | Britannica

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 …
