Abstract
Investigations of the “classical” cadmium(II) bromide and iodide complex ion systems show conclusively that in the presence of moderately strong anion-induced adsorption, apparent polarographic stability constants are larger than those determined by other methods such as potentiometry. Such systems can exhibit seemingly normal d.c. polarographic behaviour, but adsorption is readily detected by a.c. methods. The authors therefore strongly recommend that in systems in which adsorption is detected, polarography should not be used to determine stability constants. Theoretical approaches to explain the observed phenomena are discussed and it is concluded that apparently differing approaches that have appeared in the literature are in fact equivalent.
