Sulfur trioxide (alternative spelling, sul ph ur trioxide) is the chemical compound with the formula SO 3.In the gaseous form, this species is a significant pollutant, being the primary agent in acid rain. It is prepared on massive scales as a precursor to sulfuric acid.n terms of electron-counting formalism, the sulfur atom has an oxidation state of +6 and a formal charge of +3. The Lewis structure consists of an S=O double bond and two SâO dative bonds without utilizing d-orbitals. The electrical dipole moment of gaseous sulfur trioxide is zero.
