Thulium(III) hydroxide is an inorganic compound with the chemical formula Tm(OH)3.[2] It can be prepared by the addition of ammonia solution to a solution containing a soluble thulium salt.[3]
Chemical properties
Thulium(III) hydroxide reacts with acids and produces thulium(III) salts:
- Tm(OH)3 + 3 H+ → Tm3+ + 3 H2O
Thulium(III) hydroxide decomposes to TmO(OH) at elevated temperature. Further decomposition produces Tm2O3.[1]
Thulium(III) hydroxide reacts to form thulium acetylacetonate in the presence of absolute ethanol and acetylacetone.[3] The product precipitates upon cooling of the solution.
