Henter

Oxidation af en vandig opløsning af palladium(II)nitrat med ozon :

{\mathsf {2Pd(NO_{3})_{2}+O_{3}+(2n+2)H_{2}O\ {\xrightarrow {8^{o}C))\ Pd_{ 2}O_{3}\cdot H_{2}O\downarrow +4HNO_{3}+O_{2}\uparrow }}

Oxidation ved elektrolyse af en vandig opløsning af palladium(II)nitrat :

{\mathsf {2Pd(NO_{3})_{2}+(2n+3)H_{2}O\ {\xrightarrow {e^{-))}\ Pd_{2}O_{3} \cdot H_{2}O\downarrow +4HNO_{3}+H_{2}\uparrow }}

Fysiske egenskaber

Palladium(III)oxid danner et mørkebrunt pulver og er uopløseligt i vand.

Kemiske egenskaber

Nedbrydes ved opvarmning (eksplosivt):

{\mathsf {2Pd_{2}O_{3}\cdot H_{2}O\ {\xrightarrow {T))\ 4PdO+O_{2}\uparrow +2nH_{2}O))

Oxiderer saltsyre :

{\mathsf {2Pd_{2}O_{3}\cdot H_{2}O+6HCl\ {\xrightarrow {}}\ 2PdCl_{2}+Cl_{2}\uparrow +(2n+3)H_ {2}O}}
