Lutetium(III) hydroxide is an inorganic compound with the chemical formula Lu(OH)3.

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] Lutetium(III) hydroxide can react with acid and form lutetium(III) salts： While heating lutetium(III) hydroxide, it will produce LuO(OH), continued heating could produce Lu2O3.
