Scandium hydroxide: Sc(OH)3 does not appear to exist as a definite compound but ScO.OH is well established and is amphoteric like Al(OH)3.
Scandium hydroxide is thrown down as a gelatinous precipitate on the addition of an alkali to a solution of scandium chloride.
ScCl3+3NaOH-->ScO.OH + 3NaCl + H2O
The lattice of scandium hydroxide is similar to that of Y.AIO.OH.
