Abstract

A method is given for evaluating mixed stability constants by the use of ion-selective electrode potentiometry. Data are presented for the lead(II)-fluoride-chloride and fluoride-bromide systems. Mixed complexes PbFCl and PbFBr were detected with stability constants (6±2)×102 and (8±2)×102 l2 mol−2 respectively at ionic strength 1.0 mol l−1 and 25°. Study of the fluoride-iodide system was thwarted by precipitation. Anomalous polarographic behaviour prevented verification of the results by a.c. polarography.
