Synthesis of Thulium Chloride Hydrate

Dissolve an appropriate amount of thulium oxide in a 50% hydrochloric acid solution using a steam bath. Typically, the oxide dissolves completely; if residual solids remain, filter the solution. Heat the clear solution on a 75°C water bath to evaporate most of the solvent. Crystals form upon cooling. Collect the crystals via filtration and dry them in a vacuum desiccator containing granular sodium hydroxide and magnesium perchlorate under reduced pressure to obtain hydrated thulium chloride.
