Summary, etc. The corrosion inhibition of steel in 2 molar sulphuric acid solution by <em>Rose</em> extract and/or <em>Rose water</em> has been studied at 30°C using chemical (weight loss and hydrogen evolution) and electrochemical (impedance and polarization) measurements. It is found that all methods give consistent results, the inhibition efficiency increases with increasing concentration of the extract, and it shows that <em>rose </em>extract is a better corrosion inhibitor for steel than<em> rose water</em>. The polarization<em> </em>curves indicate that <em>rose</em> extract and <em>rose water</em> act as mixed-type inhibitors. The adsorption of inhibitor on the steel surface is found to obey the Langmuir adsorption isotherm model for <em>rose</em> extract and Freundlich adsorption isotherm for both <em>rose</em> extract and rose water. Thermodynamic data for the adsorption process (K<sub>ads</sub> and G°<sub>ads</sub>) were calculated and discussed.
