Infobox references

Palladium(II) nitrate is a red-brown solid that is strongly oxidizing (both the palladium(II) cation, Pd²⁺, and the nitrate anion, NO₃⁻, are strongly oxidizing) and may liberate noxious fumes upon reaction with reducing agents. It is a skin and respiratory irritant. It is normally stable at room temperature, but decomposes at higher temperatures.

Preparation

Palladium nitrate may be prepared by dissolving palladium oxide hydrate in dilute nitric acid followed by crystallization. The nitrate crystallizes as yellow-brown deliquescent prisms. Alternatively, the compound may be obtained by reacting palladium metal with nitric acid.
