Praseodymium(III) hydroxide

Praseodymium(III) hydroxide is an inorganic compound with a chemical formula Pr(OH)3.

Production The reaction between ammonia water and praseodymium(III) nitrate produces praseodymium(III) hydroxide:《无机化合物制备手册》. 朱文祥 主编. 化学工业出版社. P98~99. 【III-103】氢氧化镨（praseodymium hydroxide） Pr(NO3)3 + 3 NH3·H2O → Pr(OH)3↓ + 3 NH4NO3

Chemical properties Praseodymium(III) hydroxide can react with acid and produce praseodymium salts: Pr(OH)3 + 3 H+ → Pr3+ + 3 H2O, for example; Pr(OH)3 + 3CH3COOH forms Pr(CH3CO2)3 + 3H2O;

Praseodymium(III) hydroxide + Acetic acid forms praseodymium(III) acetate and water.
