The periodic current oscillations of Fe/HNO3 are presented in this paper. The effects of HNO3 concentration and imposed potential were investigated. The dropping method was used to change the local pH of the Fe/electrolyte interface, creating environments that favor the occurrence of current oscillations. Some interesting results were obtained and an explanation of the current oscillations is suggested.
