ABSTRACT
The aim of this paper is to present the chemical behaviour of cuprum (II) and mercury (II) in chelate complexes with L-ascorbic acid in alkaline solution. The results were interpreted by the spectroscopy method. Composition and total stability constants of the complexes were determined by Jacymirski method. In solution in with pH =9, H2 Asc forms complexes of the type [Me(Asc)2]-2; Me:L = 1:2. The complexes are of medium stability.
