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.
