Praseodymium(III) oxalate is an inorganic compound, a salt of praseodymium metal and oxalic acid, with the chemical formula Pr(C2O4)3. [1] The compound forms light green crystals that are insoluble in water. It also forms crystalline hydrates.
Praseodymium(III) oxalate precipitates out during the reaction of soluble praseodymium salts with oxalic acid:[ citation needed ]
Praseodymium(III) oxalate forms crystalline hydrates (light green crystals): Pr2(C2O4)3·(8H2O + 2.21H2O). The crystalline hydrate decomposes stepwise when heated to 800 °C (1,470 °F): [2] [3]
Praseodymium(III) oxalate is used as an intermediate product in the synthesis of praseodymium. It is also applied to colour some glasses and enamels. If fused with certain other materials, the compound colors glass an intense yellow. [4]
