What is a Sodium oxide (Na₂O)?

Sodium oxide (Na₂O) is an inorganic compound composed of sodium (Na) and oxygen (O), with the chemical formula Na₂O. It is a white or gray solid at room temperature and is highly basic. Sodium oxide is typically obtained by the reaction of sodium metal with oxygen, and it does not naturally occur in significant amounts in nature. Sodium oxide reacts with water to form sodium hydroxide (NaOH), a strong base. This reaction is exothermic and releases heat, making the handling of sodium oxide with water potentially dangerous. In industrial applications, sodium oxide is used as an intermediate in chemical reactions and plays a key role in the production of glass and ceramics by lowering the melting point of glass.

In the chemical industry, sodium oxide is also involved in the manufacture of various chemicals. Its strong basicity allows it to neutralize acids, forming salts in neutralization reactions. Therefore, sodium oxide is an essential compound in many chemical processes. The handling of sodium oxide requires caution due to its high reactivity, particularly when it comes into contact with water, as it can result in hazardous reactions. Despite its risks, sodium oxide is a valuable chemical in both industrial and chemical manufacturing sectors.
