| Abstract: | The inhibiting action of 2-mercaptobenzimidazole on the corrosion of mild steel in phosphoric acid (H3PO4) solution has been investigated by weight loss and polarization. The studies reveal that the inhibitor is effective for the inhibition of mild steel over a wide concentration range of H3PO4 solutions and retards the anodic and cathodic corrosion reactions with emphasis on the former. |
