Oxygen electrode theory

The oxygen electrode should thus, in theory, function as if it were reversible with respect to hydrogen ions. 

Some theory concerning the characteristics of membrane-covered polarographic oxygen electrodes has been presented [53].

Permeability Measurement. The general theory of gas transport in polymers and detailed discussion of the method of measurement and calculation of the permeability, diffusion coefficients have been published elswhere In this study, two kinds of permeability measurement were made. One experimental method was an adaptation of the high vacuum gas transmission technique described by Stannett and co-workers. The other experimental method for permeation of oxygen dissolved in water was an adaptation of the oxygen electrode as follows.5...

Janssen and Hoogland (J3, J4a) made an extensive study of mass transfer during gas evolution at vertical and horizontal electrodes. Hydrogen, oxygen, and chlorine evolution were visually recorded and mass-transfer rates measured. The mass-transfer rate and its dependence on the current density, that is, the gas evolution rate, were found to depend strongly on the nature of the gas evolved and the pH of the electrolytic solution, and only slightly on the position of the electrode. It was concluded that the rate of flow of solution in a thin layer near the electrode, much smaller than the bubble diameter, determines the mass-transfer rate. This flow is affected in turn by the incidence and frequency of bubble formation and detachment. However, in this study the mass-transfer rates could not be correlated with the square root of the free-bubble diameter as in the surface renewal theory proposed by Ibl (18). 

Gratifyingly (see below), various theories for the metal in the interface have found values close to this one for this quantity.] From a number of experiments, it is suggested that xHl° is between 0.08 and 0.13 V, which means that gH2°(dip) is between 0.02 and 0.07 V on a mercury electrode at the point of zero charge (oxygen end of the water molecules toward the metal).
