Formation of Sulfur Dioxide

S + O2 → SO2

Übersicht

Sulfur burns in oxygen with a characteristic blue flame to produce sulfur dioxide, a pungent-smelling gas. This reaction is the first step in the industrial production of sulfuric acid. Sulfur dioxide is also a significant atmospheric pollutant.
