Method
In sulfuric solution by titration with potassium iodate solution against starch as the indicator, iodide ions are oxidized to iodine, which in turn oxidizes sulfite ions to sulfate ions. At the titration end-point, excess iodine forms a blue complex with the indicator. The sulfite concentration is determined from the consumption of titration solution (iodometric determination).
