Molecular formula :
nature : Metal occurred pitting or crevice corrosion, the metal will reduce the potential value of certain potential below the metal surface to be protected so again to stop the corrosion potential. To protect their own potential and the corrosion resistance of metals, media, and the composition has the degree of corrosion. Pitting potential and the potential to protect the greater the margin, usually metal crevice corrosion greater tendency.
