CHEMICAL PROPERTIES
The oxide is very hygroscopic, readily absorbing moisture and carbon dioxide from the atmosphere. It is insoluble in water but dissolves in mineral acids to form salts of the La3+ cation, the only stable valence. Among La(III) salts, the carbonate, hydroxide and oxalate are insoluble in water whereas the chloride and nitrate are soluble; the acetate is sparingly soluble. Several lanthanum-rich mixed-lanthanide salts are standard products. Please request further information.
