- Chemical Laboratories, University of Allahabad, Allahabad-211 002 Manuscript received 3 August 2979, accepted 30 December 1979 Formation constants of binary and ternary complexes of the systems of the type : M-L and M-egta-L [M = scandium(III), yttrium(III) and lanthanum(III), egta= ethylene glycol-bis (ß-aminoethylether)-tetra acetic acid, L= o-cresotic acid (o-ca), m-cresotic acid (m-ca), 5-chlorosalicylic acid (csa), and 3,5-dibromosalicylic acid (dbsa)] have been determined pH-metrically at 25° and μ=-0.1M (KNO2) in 50% (v/v) aqueous-ethanol medium. The order of stabilities of ternary complexes have compared with those of corresponding binary complexes, and results discussed on the basis of coulombic interactions.
