Sodium oxide is a chemical compound. It is used as an etchant, in glass production and for polymerization.

In nature, sodium oxide does not occur freely, but only in bound form. It is widespread in this form, e.g. it is bound in numerous minerals.

Sodium oxide reacts violently with water to form sodium hydroxide

N / A2O + H2O → 2NaOH.

It is created when sodium is burned

4Na + O2 → 2Na2O

Sodium is in a ratio of 2: 1 to oxygen.
