Caption: Iron nail in dry air. Experiment to show the corrosive effects of different combinations of water and air on iron. Here the nail is in a beaker filled with air. A desiccating agent has been added to remove any moisture. Iron rusts (corrodes) in the presence of oxygen and water. In normal air this tends to happen slowly as the water content is quite low. Here all the moisture has been removed from the air so no rust (iron oxide) has formed, and the nail should stay in the same condition indefinitely.
