Brief introduction:
Cerium(III) Oxalate Hydrate
Molecular formula: Ce2 (C2O4) 3
Molecular weight: 544.29
CAS NO. :15750-47-7
Appearance: white crystalline powder, odorless and tasteless. Its anhydrous salt is monoclinic columnar crystals. When dried in a vacuum, the density is 2.2413g/cm3. 9 water salt loses 8 molecules of crystal water at 110°C. Insoluble in water, ethanol, ether, lye hydroxide, oxalic acid solution, alkali solution; soluble in dilute sulfuric acid and hydrochloric acid, hardly soluble in water, insoluble in dilute inorganic acid, but soluble when heated. When heated in a hydrogen atmosphere, the 10-water salt changes from brown to black.
