Minimizing Silver-Silver Chloride Electrode Impedance

We sought to minimize silver-silver chloride electrode impedance by chemical treatment. Chloriding pure silver electrodes lowered the impedance, as noted by Geddes [1]. Immersing the chlorided electrodes in photographic developer lowered the impedance further, as noted by Marmont [2]. A second layer of silver chloride did not result in any further reduction in impedance, as hypothesized.
