There is a growing trend to utilize plant extracts and pharmaceutical compounds as corrosion inhibitors. The inhibitive performance of extract of Adhatoda Vasika (AV) on the corrosion of mild steel in 0.5 M HCl were studied using mass loss and electro chemical measurements. Results confirmed that the extract of AV acts as an effective corrosion inhibitor in the acid environment. Potentiodynamic polarization and electrochemical impedance studies confirmed that the system follows mixed mode of
