Samples of simulated lake water are exposed to SO2(g). Two graduated cylinders containing samples of simulated lake water had CaCO3(s) added, and dissolves to form Ca2+ ions and CO32- ions. The chemical reaction of water exposed to SO2(g) is:H2O(l) + S02(g) --> H2S04(aq) (sulphuric acid) , producing Hydronium ions in solution. Hydronium ions react with the CO32- ions which then produces,options:HCO3-(aq) (weak acid)H2CO3(aq) (weak acid)HCO3-(aq) (strong acid)H2CO3(aq) (strong acid) |
