Europium(III) arsenate is an arsenate salt of europium, with the chemical formula of EuAsO4. It has good thermal stability, with its pKsp,c of 22.53±0.03.[1] It is a colorless crystal with a xenotime structure.[2]
Europium(III) arsenate can be prepared by reacting sodium arsenate (Na3AsO4) in a europium(III) chloride (EuCl3) solution:[3]
Reacting europium(III) oxide (Eu2O3) with arsenic pentoxide (As2O5) can also obtain europium(III) arsenate.[2]
