title: Determination of chelate complexes by spectrophotometry; L-ascorbic acid with cadmium (II) and zinc (II) in alkaline solution.
abstract: The chemical behaviour of L-ascorbic acid (H2Asc) with cadmium (II) and zinc (II) in alkaline medium was studied. The total stability constants of the examined complexes and their composition were determined by spectrophotometry (Jacymirsky and computer) method. An attempt has been made to explain the nature of complexes formed in the systems Cd (II)-H2Asc-H2O and Zn (II)-H2Asc-H2O and the interaction between these compounds.
