SO2 is extracted by gas in acid condition (air or nitrogen). It is fixed and oxidized in the bubbling flask, containing a diluted and neutralized solution of hydrogen peroxide. The sulphuric acid formed is titrated by a standard solution of sodium hydroxide (titration accessories not included). The free SO2 is extracted from a cold sample, while total or combined SO2 requires a heating of the sample.
