Summary In this work we report the values of electrophoretic mobility on thin layers of silica gel for the most common inorganic ions. As electrolyte 0.1 M disodium EDTA solutions, buffered at pH 4.5, 7, 10 were employed. From the kind of migration obtained we can deduce that complex formation takes place for some ions only at higher pH and whereas for others it occurs at acid pH. A third group of ions, at least, has almost zero mobility at all pH, probably because of the formation of insoluble products of hydrolysis. The different mobility values allow the realization of interesting separations, including of groups of very similar ions.
