Sodium is ordinarily quite reactive with air and the reactivity is a function of the relative humidity or water-vapour content of the air.
The corrosion of solid sodium by oxygen also is accelerated by the presence of small amounts of impurities in the sodium. In ordinary air, sodium metal reacts to form a sodium hydroxide film, which can rapidly absorb carbon dioxide from the air, forming sodium bicarbonate.
