Ytterbium(III) hydroxide is an inorganic compound with the chemical formula Yb(OH)₃.

Chemical properties

Ytterbium(III) hydroxide dissolves in acid to form a ytterbium salt:

Yb(OH)₃ + 3 H⁺ → Yb+3 + 3 H₂O

Ytterbium(III) hydroxide is decomposed by heat, first forming YbO(OH), and continuing to heat to obtain Yb₂O₃.^[1] It reacts with aluminum hydroxide oxide (AlOOH) at 1400 °C to obtain Yb₃Al₅O₁₂.^[2]
