The corrosion inhibition properties of Ocimum tenuiflorum (Tulsi) leaves extract as a potential green inhibitor of zinc corrosion in H2SO4 have been investigated employing gravimetric and thermometric techniques. The results show that different concentrations of the Ocimum tenuiflorum extract have inhibited zinc corrosion and that the inhibition efficiency has varied with the concentration of extract and temperature of experimental corrosion half-cell.
