  • SO2 testing - Brewing Forward wiki

    Acid is added to a measured sample, which shifts all of the sulfite into molecular SO 2. The molecular SO 2 (in gaseous state) is moved into a second vessel using an air pump. There it reacts with hydrogen peroxide (H 2 O 2) to form sulfuric acid (H 2 SO 4). An indicator solution is used in the second vessel.
