The effect of dihexyl sulphide as a corrosion inhibitor for Zinc in 0.5N HCl and 0.5N H2SO4 by conventional weight loss and gasometric methods. Results obtained from weight loss and gasometry methods indicate that dihexyl sulphide exhibited good composition inhibition efficiencies in both acids but performed better in 0.5N H2SO4 than in 0.5N HCl. The inhibition efficiency was found to increase with increase in the inhibitor molecules on the zinc metal surface, which obyed Temkin adsorption isotherm. The surface film formed over the zinc surface was characterized by Scanning Electron Microscope.
