Combustion, rusting and tarnishing are to be defined. Concept Introduction: Oxidation is the process in which loss of electrons takes place during a redox reaction . Corrosion is the process in which metal is corroded by the atmospheric gases. It is the slow destruction of metals. Combustion is defined as the burning of a substance in the presence of excess amount of oxygen. Combustion reactions are exothermic in nature. Rusting is defined as the process of formation of oxides of iron from iron or steel due to its reaction with oxygen or moisture. Tarnishing is defined as the process of the removal of metals by chemical reactions which results in oxides, sulfides or its metal salts.
