yellow to orange-yellow orthogonal crystals or crystalline powders. Loss of water of crystallization at 180-200 ℃. About 350 °c was decomposed into ceos04. Dissolve in a small amount of water, but in a large amount of water decomposition, precipitation of basic salts. Slowly soluble in cold inorganic acid, and soluble in hot inorganic acid. Soluble in dilute sulfuric acid.
sulfuric acid is added to Cerium hydroxide under stirring, heated, filtered, evaporated to form a crystalline film, then cooled, suction filtered, washed, dried, pure cerium sulfate tetrahydrate was obtained.
Analytical reagents for the determination of nitrites, iodides, ferrous salts and other substances of high valency which can be oxidized.
