Sodium Peroxide, Formula, Chemical Properties, Preparation, Uses

Sodium Peroxide

Sodium peroxide is an inorganic compound that is mixed with the combustible substances for heating by the process of friction. It is ignited when the excess of oxygen is occurred. Sodium peroxide is a strong base acid. This will goes to the transition phase with the unknown symmetry of the hexagonal form. It is soluble in the hydrates and metal peroxide materials. The systematic IUPAC name is known as sodium peroxide . The chemical or molecular formula of sodium peroxide is Na2O2. It is also known as disodium dioxide or solozone.

Structural Formula

This is the structural formula of the sodium peroxide:

Sodium Peroxide

Chemical Formula

The chemical formula of the sodium peroxide is Na2O2.

Preparation Method

When the sodium hydroxide is reacted with the hydrogen peroxide to form the sodium peroxide. At the moderate temperature it absorbs the oxygen by the reaction of metallic sodium. In mild heating the iodine can be sublimed. These reactions is catalyzed by the platinum or palladium crystals. In another method it is produced by passing the ozone gas on the palladium or platinum tube which is present is called sodium iodide.
