Europium(III) hydroxide is an inorganic compound with a chemical formula Eu(OH)₃.

Chemical properties[]

Europium(III) hydroxide can be prepared by reacting metallic europium with water. It reacts with acids and produces europium(III) salts:

Eu(OH)₃ + 3 H⁺ → Eu³⁺ + 3 H₂O

Europium(III) hydroxide decomposes to EuO(OH) at elevated temperature. Further decomposition produces Eu₂O₃.^[1]
