Sulfur oxyacids ions

Intensities of Aqueous Oxyacid Ions of Sulfur. Anal. Chem. Acta 1980, 117, 301. 

Nitrous and nitric acids are produced in the aqueous phase after NO2 and/or N2O3 are absorbed into solution and sulfur oxyacids, such as sulfite/bisulfite or pyrosulfite, are formed if SO2 dissolves in the solution. Interaction among oxides of nitrogen, nitrogen oxyacids, sulfur oxyacids, oxygen, and trace metal ions such as Fe(III) or Mn(II) can take place in a flue gas wet scrubber. Identifying all reactions involved in this complex system is impossible. However, important reactions must be identified and characterized in order to improve the performance of a scrubber. 

The most common oxyacid of sulfur is H2S04, sulfuric acid. In dilute aqueous solutions this substance is almost completely dissociated into ions according to the equation...
