Benzeneseleninic acid and its ammonium salt forms with scandium a white crystalline precipitate in neutral and weak acid solutions. The composition of the compound corresponds to the formula Se(C/sub 6/H/sub 6/SeO/sub 2/)/sub 3/, which may be recommended as a gravimetric form (a conversion factor for scandium is 0.0738). A method was developed for the determination of scandium by its precipitation with benzenesulfinic acid in the presence of rare earths, iron, and aluminum. The composition of the precipitate is close to the formula Sc(C/sub 6/ H/sub 5/SO/sub 2/)/sub 3/-xH/sub 2/O. For the quantitative determination the precipitate is ignited at 1000 deg and weighed as Sc/sub 2/O/sup 3/. (auth)
