Abstract

The anodic polarization behavior of nickel electrode was studied in fluoride ions containing acetonitrile medium. In the voltammetric study, a distinct anodic peak was noticed which corresponds to the formation of nickel fluoride (NiF2) film. The film formed during the first potential polarization is stable in the absence of water. With the addition of water, the solubility of NiF2 layer enhances anodic dissolution. However, the film formed in high concentration of fluoride ion is fairly stable even in presence of equi-molar quantities of water. The addition of water after of before polarization has only little influence on the anodic behavior. The competitive influence of fluoride ion and water on the stability of NiF2 film and the resistivity of this towards interfacial electron transfer are also studied
