Quantitative test for sulfur dioxide in orange juice

    Is there a quantitative test for the amount of sulfur dioxide in orange juice. Nothing too complicated, im only in year 11. Can it be done using titration?

    yes, although i cant remember the corrrect procedure from top of my head. It goes something like this, Sample is heated(with H+) with N2 bubbling thru the mixture, the gas produced is collected in a seperate flask with hydrogen peroxide and the subsequent solution is titrated with NaOH.
