properties

Physical Properties

Palladium (II) nitrate is a red-brown powder at room temperature. It is sparingly soluble in water and forms a cloudy solution as a result of hydrolysis . It is soluble in dilute nitric acid.

Chemical properties

Palladium (II) nitrate decomposes when heated. It hydrolyzes in excess water, forming a brown, basic salt. It has a strong oxidizing effect, since both the Pd 2+ ion and the nitrate ion NO 3 - are oxidizing. Crystalline palladium (II) oxide is formed by precipitation with sodium hydroxide solution .

use

Palladium (II) nitrate is suitable for the production of pure palladium and palladium (II) sulfate . .
