Holmium(III) hydroxide

Holmium(III) hydroxide is an inorganic compound with the chemical formula Ho(OH)3.

Chemical properties
Holmium(III) hydroxide reacts with acids to produce holmium(III) salts:
 * Ho(OH)3 + 3 H+ → Ho3+ + 3 H2O

Holmium(III) hydroxide undergoes thermal decomposition to HoO(OH) at elevated temperatures. Further decomposition at higher temperatures produces Ho2O3.
