Figure 2. Permeation of ClO₂ through a gelatin membrane as a function of time t.

Each point in the diagram represents a „black burst” (see Methods). V is the cumulative volume of the 0.01 M Na₂S₂O₃ titrant added before the burst and N is the amount of ClO₂ permeated until time t. T _L1 = 627 s and T _L2 = 175 s are time lags of the first and the second experiments, respectively. The concentration of ClO₂ source in the magnetically stirred aqueous solution was 1360 ppm (mg/kg) or 20.1 mM.
