6. Hydrogen sulfide gas (H2S) is the culprit for the rotten egg smell in hot springs, toots, and can be found in nuisance concentrations in some groundwaters. Hydrogen sulfide is also a weak acid dissociating to bisulfide (HS) with a pKa=7. Dissociation reaction: H2S(q)H++HS a. Hydrogen sulfide gas (not the ion bisulfide) can be removed via air stripping, where the gas moves form the water to the air. Please complete the CTeulfide vs pH plot to illustrate how the fractionation between hydrogen sulfide and bisulfide change with pH and use the plot to explain why air stripping would be more effective at a high or low pH. b. What would the pH of the water need to be for there to be 100 times more hydrogen sulfide than bisulfide
