Answer» 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)

Answer»

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)
