✦ Synopsis


Polarization curves for the anodic oxidation and cathodic reduction of Ni(OH), electrodes at constant current have been obtained, and also Tafel curves for the anodic process. A comparison is made between the electrochemical behaviour of freshly prepared and of recrystallized Ni(OH)2 layers, and the extent to which the differences may be correlated with structural charges in the solid phase is discussed. R&m&--Etablissement des courbes de polarisation d'oxydation anodique et de reduction cathodique d'&ctrodes a Ni(OH),, a courant constant, ainsi que des courbes de Tafel pour le processus anodique. Des differences, en partie attribuables a des charges structurales dans la phase solide, se manifestent entre Ni(OH), fraichement prepare ou bien recristallise. Zusammenfassung-Es wurden Polarisationskurven der amperostatischen anodischen Oxydation und kathodischen Reduktion von Ni(OH)l-Elektroden aufgenommen sowie Tafel-Kurven des anodischen Prozesses bestimmt. Man vergleich das elektrochemische Verhalten von frisch hergestellten gegentiber rekristallisierten Nickel-hydroxydSchichten, und die Moglichkeiten der Interpretation durch strukturelle Aenderungen in der festen Phase werden besprochen.

The polarographic characteristics of the nickel(H) ion in the presence of six heterocyclic species are reported; although slight mechanistic differences exist in reduction behaviour between members of the pyridine and pyrazole series, they share the common feature that the rate-determining step invo
