Chemical Properties
The hygroscopic oxide is insoluble in water but will dissolve in mineral acids to form salts of the Nd+3 cation that are usually pink-violet in color. Among Nd(III) salts, the carbonate, hydroxide and oxalate are insoluble in water whereas the chloride and nitrate are soluble; the acetate is sparingly soluble.

The color of this oxide is sensitive to slight variations in particle size, cerium and praseodymium contents.
