Lutetium(III) hydroxide is an inorganic compound with the chemical formula Lu(OH)3.
Production[edit]
Reacting lutetium chloride and alkalis will first produce Lu(OH)2Cl, then it will become Lu(OH)2.5Cl0.5. Finally, the reaction will produce Lu(OH)3.[2]
- LuCl3+2 NaOH→Lu(OH)2Cl+2 NaCl
- Lu(OH)2Cl+0.5 NaOH→Lu(OH)2.5Cl0.5+0.5 NaCl
- Lu(OH)2.5Cl0.5+0.5 NaOH→Lu(OH)3+0.5 NaCl
Chemical properties[edit]
Lutetium(III) hydroxide can react with acid and form lutetium(III) salts:
- Lu(OH)3 + 3 H+ → Lu3+ + 3 H2O
While heating lutetium(III) hydroxide, it will produce LuO(OH), continued heating could produce Lu2O3.[1]
