Аннотация:(59)Co NMR spectra were measured to determine the stability constants of ion aggregates formed by an ethylenediaminetetraacetato anion [CoEdta](-) and alkali metal cations. Cathode polarization curves were measured for Na[CoEdta] solutions containing various amounts of Na(2)SO(4). The values determined for the association constants are approximately ten times those typical of singly charged anions. The observed relationships between the [CoEdta](-) reduction rate and the base electrolyte concentration are caused by the preferential participation of ion aggregates, rather than complex anions, in electrochemical processes.
