Abstract
The electroreduction kinetics of silver sulfite complexes was investigated by electrochemical fast Fourier transform (FFT) impedance spectroscopy (0.061-1500Â Hz). The time dependences of the real and imaginary components of impedance were determined in a solution containing 0.05Â M Ag (I) and 1Â M Na2SO3. The mean duration of silver ad-atom diffusion on the surface to the nearest crystallization centre was calculated: during the first 210Â s of contact with the electrolyte, these values increase from 0.66 up to 1.77Â s; thereafter, this variation stabilizes and the mean duration of silver ad-atom diffusion reaches an almost constant value (1.56Â s).
