Scandium hydroxide, Sc(OH)3






Scandium hydroxide, Sc(OH)3, is obtained as a white, bulky, gelatinous precipitate by adding ammonium or sodium hydroxide to a solution of a scandium salt. When dried in the air it has a composition corresponding to the above formula. The hydroxide is a rather weak base, with a marked tendency to form basic salts. It readily dissolves in acids, forming salts which have a sweet, astringent taste.
