Bildungskonstanten von Komplexen der 3-Hydroxynaphthalin-2-carbonsäure mit Pr(III), Nd(III), Gd(III), Dy(III), Er(III) und Yb(III)

The stability constants of the complexes of 3-hydroxynaphthalene-2-carboxylic acid with some lanthanides have been obtained potentiometrically in aqueous dioxane (50%,V/V) at three temperatures and keeping the ionic strength at 0.1M (KNO₃), usingIrving-Rossotti titration technique. The values of overall changes in G°, H°, and S° have also been evaluated.
