## Abstract The oxidation of trivalent chromium in aqueous solution using atmospheric oxygen has been studied. Thermodynamically it has been shown that the oxidation is feasible at __pH__ values greater than 4. In practice the oxidation could be made to proceed only in very alkaline solution with t
The passivity of pure chromium has been studied in sulphuric acid solutions as a function of concentration (l-18M), acidity, activity of water and the nature of the anions in the electrolyte. The passivity phenomena of this metal have been investigated using anodic polarization measurements and X-ra
