Abstract
The formation constants of the complexes of Mg2+, Ca2+, and Sr2+ with 2,3-diphosphoglycerate have been determined with pH-methods according to Schwarzenbach. The enthalpies of these reactions were obtained by microcalorimetric measurements. They are positive as well as the entropies showing that the complex formation is only caused by an increasing entropy. A comparison is made with the corresponding values obtained by ANDEREGG 1 for the tripolyphosphate.
