Abstract
IN carrying out research in these laboratories on the corrosion of tin in anaerobic fruit acids, information was required on the thickness of the natural oxide film on tin. Since there appeared to be no published information about the thickness of tin oxide films, it was necessary to measure it, and for this purpose electrometric reduction has been found suitable. This method1,2 is generally considered to be applicable only to metals more electronegative than hydrogen ; but it succeeds for tin because of its high hydrogen overpotential. At room temperature the oxide film on tin probably consists of stannous oxide3,4, and we have calculated our results on this basis.
