• The stability constants of 5-nitrosalicylic acid (5-NSA ) and 5-sulfosalicylic acid (5-SSA) complexes of Sc(III)were determined by potentiomeric pH titration. ML and ML_2 type first and second complexes were observed in the solutions of 5-NSA and 5-SSA with Sc(III) at 25℃ in I=0.1M ionic medium. The stability constants of Sc(III)-5NSA and Sc(III)-5SSA systems were also investigated by spectrophotometry to determine the stoichiometries of the complexes formed in the reactions. Our results showed that Sc(III)-5SSA complexes are more stable than the Sc(III)-5NSA complexes in aqueous solutions.
