sodium oxide

chemical compound
Also known as: soda, sodium monoxide

Quick Summary

Sodium oxide (Na2O) is a hygroscopic, amorphous monoxide that reacts vigorously with water to produce sodium hydroxide. It is primarily obtained as an intermediate in the manufacture of sodium peroxide. Sodium oxide is a component of water glass, a compound that also includes silica (SiO2) and is soluble in water. Water glass is produced by heating soda ash (sodium carbonate) and silica sand, releasing carbon dioxide and forming sodium silicate. This compound is used in detergents, as a binder and adhesive, and in water treatment. Sodium itself is a soft, silvery-white alkali metal, the sixth most abundant element on Earth, commonly found in compounds like sodium chloride (salt).123
