  • The Ripper Titration: Recent Improvements in Measuring SO2

    Each mmol of H2O2 reacts with one mmol of SO2, so this equals 0.1 mmol of SO2. Each mmol SO2 reacts with one meq of the SO2 titrant, whose strength is 0.0156 meq/ml. So you have 0.1 meq/0.0156 = ~ 6 mL]. So unless your original titration was more than 6 mL, one drop should be enough. You can add 2 if
