Damp carbonic acid and oxygen--oxidation very rapid. Dry and damp oxygen and ammonia--no oxidation. Indicating that oxidation is principally due to the presence of carbonic acid with oxygen. Chemical News, 1870-1871. When distilled water was deprived of its gases by boiling, and a bright blade introduced, it became in the course of a few days here and there covered with rust. The spots where the oxidation had taken place were found to mark impurities in the iron, which had induced a galvanic action, precisely as a mere trace of zinc placed on one end of the blade would establish a voltaic current. Kent has shown that the rusting of iron railroad bridges is sometimes greatly accelerated by the action of the sulphurous gases and the acids contained in the smoke issuing from the locomotive, and that sulphurous acid rapidly changes to sulphuric acid in the presence of iron and moisture, thus greatly accelerating corrosion. Iron and steel absorb acids, both gaseous and liquid, and are therefore probably permanently injured whenever exposed to them. Calvert experimented upon iron immersed in water containing carbonic acid, in sea water, and in very dilute solutions of hydrochloric, sulphuric, and acetic acids. A piece of cast iron placed in a dilute acetic acid solution for two years, was reduced in weight from 15.324 grammes to 3 grammes, and in specific gravity from 7.858 to 2.631, while the bulk and outward shape remained the same. The iron had gradually been dissolved or extracted from the mass, and in its place remained a carbon compound of less specific weight, and small cohesive force. The origin...
