Abstract
Conductances, densities, partial molal volumes, solubilities, and transference numbers were measured for scandium chloride, nitrate, and perchlorate. The stability constants of the chelates formed by the rare earths and scandium with ME(l,2-bis- STA2-di(carboxymethyl)aminoethoxy!ethane) and DE(2,2 -bis- STAdi(carboxymethyllaminoldiethyl ether) were measured polarographically. In addition, the stability constants of the scandium chelates of HEDTA (N -hydroxyethyl)-ethylenediamine-N,N,N -triacetic acid), EDTA- (ethylenediamine-N,N,N ,N -tetraacetic acid), DCTA (l,2-diaminocyclohexane-N,N,N ,N -tetraacetic acid), and DE TPA ((carboxymethyl)-bis- (2-di- (carboxymethyl)aminoethyllamine) were also measured.
