Abstract
The validity of the widely used polarographic method for the determination of stability constants is considered for adsorbable ligands. A polarographic study of the stability constants of the lead(II)-halides indicates that results become less reliable down the group. Agreement with accepted values for the fluoride and chloride systems is good. However, the bromide and iodide stability constants are significantly higher than values obtained by other techniques. This is attributed to complexation with adsorbed ligand in the double layer. It is concluded that polarographically determined stability constants of metal ions with adsorbable ligands are liable to be higher than “true” values. Such systems would be better evaluated by other techniques.
