Palladium(II) oxide is the chemical compound of formula PdO. It is the only well characterised oxide of palladium.[1] It is prepared by reacting the metal with oxygen below 875C as PdO dissociates above about 900°C. It is insoluble in acids.[1] The hydrated oxide, PdO.nH2O can be produced as a dark-yellow precipitate by adding alkali to a solution of palladium nitrate,Pd(NO3)2.[1]
