Abstract
The complex formation between W(VI) and malic acid (H2M) has been investigated polarimetrically in excess malic acid. The formation of three different complexes is confirmed. The stoichiometry and the degree of condensation of these complexes can vary depending on the acidity. Furthermore, the results obtained show that both tartaric and malic acids behave similarly in forming complexes with W(VI). The formation constant of the complex [O2W(OH)2(M2)]4− has been determined by two different methods.Keywords
