Abstract
FROM a series of investigations of the rest potential on bright platinum electrodes1 in oxygen-saturated acid solutions, it was suggested that the reversible oxygen potential of 1.229 V (ref. 2) is not ordinarily observed because platinum is not inert to such an electrolyte, and the system never comes to equilibrium. The Pt-O-acid system, then, is a polyelectrode3, and the rest potential is a mixed potential4. It was further suggested that, if an electronically conducting surface which is inert to oxygen-saturated acid solution could be obtained, the reversible potential should be observed because, then, the system would be a simple electrode.
