Contents

Synthesis

Dissolving metallic erbium in nitric acid:

Er + 6 HNO3 → Er(NO3)3 + 3 NO2 + 3 H2O ↑

Dissolving erbium oxide or hydroxide in nitric acid:

Er(OH)3 + 3 HNO3 → Er(NO3)3 + 3 H2O ↑

Reaction of nitrogen dioxide with metallic erbium:

Er + 3 N2O4 → Er(NO3)3 + 3 NO ↑

Physical properties

Erbium(III) nitrate forms pink hygroscopic crystals.

Forms crystalline hydrates of the composition Er(NO3)3·5H2O.

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.

Nitric acid is an inorganic compound with the formula HNO3. It is a highly corrosive mineral acid. The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%.
