ABSTRACT
The inhibition of mild steel corrosion in 1 M sulphuric acid media by ethanolic extracts of Ipomoea batatas was investigated using the gravimetric and gasometric methods. The extracts recorded an inhibition efficiency of 61.1 % and 52.6 % at room temperature for the gravimetry and the gasometry respectively. The inhibition process was initiated by the physical adsorption of the inhibitor extracts to the metal surface and the data obtained fitted very well into the Langmuir adsorption isotherm.
