Scandium: history, properties, reactions, risks and uses
The oxide Sc 2O 3 and the hydroxide Sc(OH) 3 are amphoteric: Sc(OH) 3 + 3 OH → [Sc(OH) 6] (scandate ion) Sc(OH) 3 + 3 H + 3 H 2O → [Sc(H 2O) 6] α- and γ-ScOOH are isostructural with their aluminium hydroxide oxide counterparts. Solutions of Sc in water are acidic due to hydrolysis. The halides ScX3, where X= Cl, Br, or I, are very soluble in water, but ScF3 is insoluble. In all four hali… WebIn compounds of scandium (where known), the most common oxidation numbers of scandium are: 3. Hydrides.
