[Chemistry Class Notes] on Sodium Oxide Pdf for Exam

When it comes to Chemistry, compounds are very common. You will get to relate yourself through various aspects of the studies. Compounds are simple molecules that are made up of two or more elements. By looking at the name or chemical formula, one can find out what are the elements included in the compound. One of the examples is Sodium Oxide.

The name suggests that Sodium Oxide is a source of Sodium that is highly insoluble and thermally stable. It is the best use for optic, glass, and ceramic applications. The compounds that are oxidized are conductive to electricity. However, there are certain perovskite structures of oxides that are electronically conductive. For this reason, it finds its application in the cathode of oxidized solid fuel cells and in the generation system of oxygen. Sodium Oxide is a form of a compound that contains at least one O₂ anion and one metallic cation.

How are they Useful for Normal Applications?

Sodium Oxide stays insoluble in water or other aqueous solutions. This makes it extremely stable for making ceramic structures, clay bowls, light-weight structural components in the industry of aerospace, and advanced electronics. It is also used for making fuel cells due to the properties of ionic conductivity. The compounds are basic anhydrides, and therefore, react well with acids. Sodium Oxides are available in pieces, pellets, tablets, sputtering targets, and nanopowder.

Na₂O Structure

The Na₂O structure is a bit complex as the molar mass is 61.98g mol^–1. A single oxygen atom makes up the oxidization, and it has a couple of ionic bonds with two sodium atoms. The structure of the molecule seems like an antifluorite crystal, and thus, the Na atoms coordinate 4 O₂ atoms. 

Preparation of Sodium Oxide

Sodium Oxide is produced with the reaction of sodium hydroxide and metallic sodium. It can also be formed from sodium peroxide or sodium nitrate. However, this reaction will produce hydrogen along with sodium oxide. The chemical formula is:

Sodium oxide can also be formed from thermal decomposition of sodium carbonate at 850°C. This produces carbon dioxide along with sodium oxide. The chemical formula is:

Chemical Properties of Sodium Oxide

Sodium Oxide produces Sodium Hydroxide when it reacts with water. This reaction is violent due to highly exothermic abilities. This is the reason; it is suggested to keep sodium oxide out of the reach of the water. The chemical formula is:

Na₂O + H₂O > 2NaOH

The alkali oxides M₂O (M = Na, Li, Rb) helps in crystallizing that antifluorite structure. Therefore, the position of the cations and anions gets reversed relatively when compared with the position of CaF₂. This happens due to sodium ions that coordinate tetrahedrally with 4 iron oxides and cubical oxides that coordinate with 8 NA (sodium) ions.

Health & Safety Information For Sodium Oxide : Signal word is Danger; Hazard Statement is H271-H314; Hazard Codes O, C and the Risk Codes are 8-14-35.

Chemical properties of Sodium Oxide

Sodium Oxide produces Sodium Hydroxide when it reacts with water and this reaction is violent because of the highly exothermic abilities. It is suggested that  sodium oxide should be  out of the reach of the water.

The chemical formula is: Na₂O + H₂O > 2NaOH . The alkali oxides M₂O (M = Na, Li, Rb) helps in crystallizing that antifluorite structure. Thus, the position of the cations and the anions get reversed relatively when it is compared with the position of CaF₂. This happens because of  sodium ions which coordinate tetrahedrally with 4 ion oxides and cubical oxides that coordinate with 8 NA (sodium) ions.
