What is Oxidation

08/02/2018 0183 32However, when iron reacts with oxygen, it becomes rust, also known as iron oxide. Unlike unoxidised iron, rust is a brittle powderlike substance. The process of rusting requires three elements: water, oxygen, and iron. When oxygen combines with metal, electrons are released. Water behaves as an effective electrolyte, which the newly liberated electrons travel through towards the hode a
