This current research focuses on the protective mechanism of mild steel when exposed to 1M hydrochloric acid solution in the presence of synthesized 1,1,4,4-tetramethyl-1,4-diocty lethylenediammonium bromide (TDEDB) as an inexpensive inhibitor using weight loss studies. The following parameters namely effect of inhibitor, the effect of temperature and the effect of pH were evaluated at different concentrations and conditions. It was revealed that the coverage of the inhibitor and the interaction over the mild steel is by the process called adsorption. A remarkable improvement was observed by the addition of inhibitor when compared to blank solution. More over increasing the concentrations of synthesized inhibitor played a vital role and the same was proven by the weight loss methodology. It evidences that at 250 ppm the maximum adsorption occurs on the mild steel which results in curtailment of the corrosion reaction.
