The calculation for SO2 solubility is as a function of pH. If SO2 alone (no acids or bases added) comes into contact with water droplets, the composition is given approximately at a pH where [H+] = [HSO3-] (see Figure 10.3a). The exact proton condition or charge balance condition is TOT H = (H+) - (HSO3-) - 2(SO32-) \u2013 [OH-] = 0. This condition applies to the following composition: pH = 4.9, [HSO3-] = 1.2 \u00d7 10-6 M, [SO2 \u00b7 H2O] = 3.7\u00d7 10-8 M, [SO32-] = 8 \u00d7 10-8 M. b. For this part we have pH = 5.65, [H2CO3 ] = 2.1 \u00d7 10-5 M, [HCO3-] = 2.2 \u00d7 10-6 M, [CO32-] = 2.7 \u00d7 M. The answer to question (b) is obtained by plotting the corresponding diagram for CO2 where [H+] = [HCO3-]. c. The answer to question (c) is obtained by superimposing the plots for SO2 and for CO2.
