Mixed complexes of Ni(2+) or Zn(2+) and citric acid with 2,2'-bipyridyl in aqueous solution.
The stability constants of ternary Ni(2+) or Zn(2+) complexes with 2,2'-bipyridyl and citric acid have been determined by means of pH-titrations at 25.0 +/- 0.2 degrees and an ionic strength of 0.1M (KNO(3)). The stability constants of ternary complexes have been compared with those of similar ternary species.
