Praseodymium selenate, Pr2(SeO4)3

The octahydrate, Pr2(SeO4)3. 8H2O, crystallises from cold aqueous solutions, and the pentahydrate, Pr2(SeO4)3.5H2O, from hot solutions. The double salt praseodymium potassium selenate, Pr2(SeO4)3.3K2SeO4.4H2O, is somewhat more soluble than the double sulphate (von Scheele).
