Lanthanum Sulfate La2(SO4)3 nH2O CAS 57804-25-8 Used As A Preservative
Name: Lanthanum sulfate, Lanthanum sulfate hydrate Molecular formula: La2(SO4)3·nH2O
CAS: 57804-25-8 Molecular weight: 566
Description: Lanthanum sulfate is the most common octahydrate, colorless salt is hexagonal crystal, dehydrated at 500 ℃, alkali salt formed at 700 ℃, and various sulfate double salts can be formed with alkali metal sulfate. La (HSO4) 3 is formed in sulfuric acid and sulfide is formed when heated under the flow of hydrogen sulfide. When lanthanum hydroxide or lanthanum oxide is dissolved in sulfuric acid, lanthanum sulfate hydrate can be obtained. Then, when lanthanum sulfate hydrate is slowly heated, the anhydrous lanthanum sulfate can be obtained.
