Chemical properties

Erbium(III) hydroxide reacts with

acids An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen cation, H+), known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the ...

and produces erbium(III) salts: : Er(OH)₃ + 3H⁺ → Er³⁺ + 3H₂O Erbium(III) hydroxide decomposes to ErO(OH) at elevated temperature. Further decomposition produces Er₂O₃.
