Abstract : ‎ The inhibitive effect of water and alcoholic extracts of Medicago Sative (MS) on the ‎corrosion of steel in 2.0 M H2SO4 containing 10% EtOH has been studied using ‎chemical (weight loss (ML), hydrogen evolution(HE)), electrochemical ‎‎(potentiodynamic polarization (PDP) and impedance spectroscopy (EIS)) techniques. ‎Also, scanning electron microscopy (SEM) is used to support the obtained results. The ‎results showed that the inhibition efficiency increases with the increase of M. Sative ‎‎(MS) concentration. The water and alcoholic extracts of MS plant act as mixed type ‎inhibitors with nearly the same efficiency. The inhibition action of M. Sative (MS) ‎extracts was discussed in terms of their horizontal adsorption on the metal surface. The ‎adsorption follows Langmuir adsorption isotherm.‎
