Dysprosium(III) hydroxide is an inorganic compound with the chemical formula Dy(OH)3.

Chemical properties[edit]

Dysprosium(III) hydroxide reacts with acids and produces dysprosium(III) salts:

Dy(OH)3 + 3 H+ → Dy3+ + 3 H2O

Dysprosium(III) hydroxide decomposes to DyO(OH) at elevated temperatures. Further decomposition produces Dy2O3.[1] The reactions are:[2]
