Abstract
Some small stability constants were determined using a Cl- ion selecti ve electrode. Two types of complexes were studied: a) metal ion - chlo ride complexes (Mg2+, Ca2+, Zn2+), and b) protonated amine - chloride complexes (diethylenetriamine, tetraethylenepentamine). Reliable resul ts were obtained for all the systems considered. Comparisons were made between our results and those reported in literature (metal complexes ), and with pH-metric formation constants (protonated amine complexes) .
