Infobox references

Erbium(III) nitrate is an inorganic compound, a salt of erbium and nitric acid with the chemical formula Er(NO3)3.[1][2][3] The compound forms pink crystals, readily soluble in water, also forms crystalline hydrates.[4][5]

Synthesis

Dissolving metallic erbium in nitric acid:

[math]\displaystyle{ \mathsf{Er + 6HNO_3 \ \xrightarrow{}\ Er(NO_3)_3 + 3NO_2 + 3H_2O\uparrow } }[/math]

Dissolving erbium oxide or hydroxide in nitric acid:

[math]\displaystyle{ \mathsf{Er(OH)_3 + 3HNO_3 \ \xrightarrow{}\ Er(NO_3)_3 + 3H_2O\uparrow } }[/math]

Reaction of nitrogen dioxide with metallic erbium:

[math]\displaystyle{ \mathsf{Er + 3N_2O_4 \ \xrightarrow{}\ Er(NO_3)_3 + 3NO\uparrow } }[/math]

Physical properties

Erbium(III) nitrate forms pink hygroscopic crystals.

Forms crystalline hydrates of the composition [math]\ce{ Er(NO3)3*5H2O }[/math].

Both erbium(III) nitrate and its crystalline hydrate decompose on heating.

Dissolves in water and EtOH.[6]

Chemical properties

The hydrated erbium nitrate thermally decomposed to form ErONO3 and then to erbium oxide.

Applications

It is used to obtain metallic erbium and is also used as a chemical reagent.
