| Abstract: | A comparison of the behavior of gold, platinum and palladium indicating electrodes in various strongly oxidizing solutions with the behavior observed when these electrodes are oxidized anodically reveals that the same reaction are occurring at the electrodes These reactions are attributed to oxide (or hydroxide) film formation because the potentials at which these various reactions occur agree reasonably well with the potential of known oxide-metal transitions The present study emphasizes the transient potential-time response of an indicating electrode when immersed in a strongly oxidizing solution It is concluded that all “inert” indicating electrodes undergo stepwise chemical oxidation in strongly oxidizing media. |
