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,
