Abstract : The effect of chloride ion addition on the corrosion and corrosion inhibition of mild ‎steel in 1.0 M sulfuric acid (H2SO4) containing 10% ethanol (EtOH) at 30°C in the ‎absence and presence of aqueous and/or alcoholic extracts of Zizyphus spina-christi ‎‎(ZSC) plant have been investigated using chemical and electrochemical measurements. ‎The addition of chloride ions leads to stimulation of corrosion at ≤ 10–4 M of chloride ‎ions, but at concentrations > 10–4 M chloride, an increase in the chloride concentration ‎produces corrosion inhibition of mild steel. A synergistic effect was observed between the ‎chloride ions and the studied extracts. Experimental results suggest that the presence of ‎chloride ions stabilized the adsorption of ZSC extract molecules on the mild steel surface ‎and therefore improved the inhibition efficiency of ZSC. The synergistic behavior of the ‎chloride ions and extract components can be attributed to cooperative adsorption or ‎competitive adsorption. ‎
