Erbium(III) hydroxide is an inorganic compound with chemical formula Er(OH)₃.

Chemical properties

Erbium(III) hydroxide reacts with acids and produces erbium(III) salts:

Er(OH)₃ + 3 H⁺ → Er³⁺ + 3 H₂O

Erbium(III) hydroxide decomposes to ErO(OH) at elevated temperature. Further decomposition produces Er₂O₃.
