Abstract
The solubilities of crystalline neodymium iodate dihydrate and amorpho us neodymium iodate anhydride in water at 298.2 K were measured iodome trically using the supersaturation method. The recommended solubility of neodymium iodate in water at 298.2 K is 1.03 x 10(-3) mol.dm-3. Anh ydrous iodate of an amorphous type was prepared by thermal dehydration of the iodate dihydrate. During the measurement the amorphous iodate was recrystallized to the crystalline iodate. Thus, the solubility obt ained agreed well with the above value.
