Sodium Oxide Formula

The chemical formula for sodium oxide is Na2O. This means that each molecule of sodium oxide contains two atoms of sodium (Na) and one atom of oxygen (O), which are held together by ionic bonds. When sodium oxide is dissolved in water, it forms sodium hydroxide (NaOH), which is a highly alkaline solution commonly used in industry and laboratory settings. Sodium oxide is also a component of many glasses and ceramics due to its ability to lower the melting point of silica-based materials.
