Scandium nitrate, Sc(NO₃)₃

Scandium nitrate, Sc(NO₃)₃, crystallises from a neutral aqueous solution as colourless, deliquescent, prismatic crystals of the tetrahydrate, Sc(NO₃)₃.4H₂O, soluble in alcohol. The tetrahydrate becomes pasty and anhydrous at 100°. Basic salts of the formulae Sc₂O₃.2N₂O₅.3H₂O and Sc₂O₃.2N₂O₅ have also been described (Crookes).

The nitrate is readily decomposed by heat with the production of basic scandium nitrates, and finally of scandia.
