Measurement of sulfur dioxide SO2 in wine - The …

Description: Sulfur dioxide is sparged from an acidified wine sample in an air stream and trapped in a solution of hydrogen peroxide which oxidises the sulfur dioxide to sulfuric acid. The sulfuric acid formed is then titrated with standardised sodium hydroxide, and the amount used is proportional to the amount of sulfur dioxide in the wine.
