Chemical compound

Praseodymium sulfate is a Pr compound with formula Pr2(SO4)3. It is an odourless whitish-green crystalline compound. The anhydrous substance is somewhat hygroscopic. It has three well-defined hydrates: praseodymium dihydrate, praseodymium pentahydrate, and praseodymium octahydrate. When crystallized from aqueous solutions, the octahydrate is formed as green transparent crystals.

Properties

Praseodymium sulfate is stable under standard conditions. At elevated temperatures, it gradually looses any crystal water present, whereas its colour becomes more whitish. Like all rare earth sulfates, its solubility decreases with temperature, a property once used to separate it from other, non-rare earth compounds.
