Formation of Sodium Peroxide

2Na + O2 → Na2O2

Descripción general

When sodium burns in excess oxygen, it forms sodium peroxide rather than sodium oxide. This yellowish-white compound is a powerful oxidizer. Unlike the lighter alkali metals, sodium preferentially forms the peroxide due to the size ratio of the ions.
