The ionic composition of an iminodiacetate electrolyte as a function of the solution composition and pH has been determined. Such kinetic parameters as exchange currents and apparent transfer coefficients of the electroreduction of a palladium (II) bis-iminodiacetate complex from an electrolyte containing an excess of a ligand have been calculated. The rate of the electrode process has been shown to be controlled by the diffusion of reduced ions to the electrode surface and by the electron-transfer reaction. An opportunity of using an iminodiacetate electrolyte for palladium plating so as to deposite fine-crystalline ductile palladium coatings adherent to the base has been examined.
