The rusting of iron is an expensive process. It is estimated that the deterioration of iron due to corrosion costs billions of dollars a year in Canada. The process is simple enough in terms of chemistry. Iron reacts with oxygen from the air to form iron oxide. This is termed an electrochemical reaction because the oxygen actually steals electrons from the iron.</p> Mon, 06 May 2013 21:47:47 +0000 Joe Schwarcz PhD 1931 at /oss
