Chemical compound

Praseodymium(III) nitrate is any inorganic compound with the chemical formula Pr(NO3)3·xH2O. These salts are used in the extraction and purification of praseodymium from its ores. The hexahydrate has been characterized by X-ray crystallography.

Praseodymium nitrate can be prepared by treating praseodymium oxide with nitric acid:

Pr2O3 + 6 HNO3 → 2 Pr(NO3)3 + 3 H2O
