Abstract
Abstract Comparative studies on the behaviour of ethylthioglycolic(I), thiodiglycolic (II), β-ethylthioethylenethioglycolic(III) and ethylene-bis (thioglycolic)(IV) acids towards metallic ions in aqueous solutions are described. Complexes are formed with Pd(II), Cu(II), Hg(II) and Ag(I) (“soft” Lewis acids). The stoichiometry of complex formation was studied by conductimetric titrations. Spectrophotometric data on the palladium(II) complexes with the four ligands are presented. Ligands III and IV offer promising analytical applications.
