摘要：

The effect of chloride ions on the dissolution and passivation of iron in 1 M sodium acetate solution, pH 5, has been studied using voltammetric and rotating ring disc electrode (RRDE) techniques. Soluble Fe(II) and Fe(III) species have been detected during the active-to-passive transition and pitting potential regions. The addition of chloride ions at higher concentrations than 700 ppm in this medium causes the rupture of the anodic film accompanied by pitting corrosion of Fe.
