The mechanism of oxygen ionization on silver in alkaline solutions has been investigated by the methods of triangular and trapezoidal voltage pulses as well as by the method of applying triangular voltage pulses on the rotating disk electrode with a ring. The process occurs with the participation bo

β¦ Synopsis
The ionization of oxygen in alkaline solutions on a nickel substrate is examined, with special reference to the state of the nickel surface. If nickel is maintained at above cc -0.15 V es hydrogen in the same solution, oxygen begins to be adsorbed: above +0-l V a phase oxide such as Ni(OH)$ is probably formed. The ionization of oxygen slows down (at any one potential) with increasing oxidation of the electrode.

L'ionisation de l'oxygene diminue lentement (51 n'importe quel potentiel) quand crolt l'oxydation de l'electrode.
