Method/Apparatus/Procedure:

The analytical method was used. The solubility of sulfur dioxide was studied in a 50 mL buret equipped with a water jacket. Sulfur dioxide was bubbled at a slow flow rate approximately 60 mL/min with the gas flow being from bottom to top of the buret. The gas exited through a spiral condenser in order to avoid excessive loss of acetonitrile. The sulfur dioxide concentration after saturation was measured by titrating excess iodine with standard thiosulfate solution using starch as the indicator.
