The purpose of this study is to investigate the effect of an inhibitor Morringa Leaves on the corrosion inhibition potential of mild steel, using Moringa leaves alcoholic extract. The study was carried out using the weight loss technique. The results obtained show that Moringa leaves alcoholic extract as potential inhibitors for mild steel corrosion in 0.5 M Sulfuric (H2SO4). An acidic environment was created to act as a catalyst enhancing the corrosion process. These experiments were all carried out at temperatures of 40 and 50 °C. The results obtained showed that the inhibition efficiency of the extract increases with an increase in the concentration of the extract. The best optimum efficiency in both cases was obtained from 40 ml concentration of Moringa alcoholic leave extract with inhibition efficiency of 75.19 %. The effects of inhibitor concentration on the corrosion rate of low steel have been found to increase with inhibitor concentration at temperature 40 and 50 °C. This experimental condition ensured that the catalyst was the only driving force in the corrosion process. These results obtained here are largely consistent with other studies using plant extract that show that corrosion inhibition is highest (or most efficient) at the highest concentration of the extracts in solution.
