The Sulfuric acid,dysprosium(3+) salt (3:2), octahydrate (8CI,9CI), with the CAS registry number 10031-50-2, is also known as Dysprosium(III) sulfate. This chemical's molecular formula is Dy₂H₁₆O₂₀S₃ and molecular weight is 757.31. What's more, its IUPAC name is Dysprosium(3+) trisulfate octahydrate. In addition, the dust of this chemical can not be breathed. And you should avoid contacting with skin and eyes. This chemical could be produced through the following way:  the high pure Dy₂O₃ could be put in dilute hydrochloric acid and then react with some more dilute sulfuric acid. After that, a large mount of 95% C₂H₅OH is added, and Dy₂H₁₆O₂₀S₃·8H₂O crystal can be precipitated. More over, the chemical will be filtered and washed by 95% C2H5OH to get pure Dy₂H₁₆O₂₀S₃.
