✦ Synopsis
The minimum presented by the polarograms of the reduction of Cu(I1) in Li+, Na+ and K+ citrate is analysed in order to determine the charge of the reacting species and the coefficient of transfer, OL, of the process. The results obtained allow the participation of thecomplex anions (Cu,Cit,)'-and (CuCita)4in dilute and concentrated citrate solutions to be established, respectively, as well as a cation-reacting anion interaction, increasing in theorder K' r Na+ r Li+. The value of the coefficient of transference D! = 0.40 is in agreement with that found by other techniques.
