Corrosion is the process by which iron is oxidized by elemental oxygen. therefore oxygen is the (oxidizing / reducing) agent and (gives / accepts) electrons.
Oxygen is the oxidizing agent and accept electrons
Explanation:
Corrosion is an example of a redox reaction which involves both reduction and oxidation process.
During corrosion a metal loses electrons and becomes oxidized to form a metal ion. Therefore, oxygen is the oxidizing agent since it undergoes reduction by gaining electrons.
Therefore, during corrosion of iron, iron is the reducing agent and gives electrons, while oxygen is the oxidizing agent and accepts the electrons.
