Also, read my cited reference on the attack of organs including the brain, now that is troubling. So, one may not really have an accurate conception of the magnitude of one's time exposure to the gas. Calculate the pH at the equivalence point in the titration of 30.0 mL of 0.25 M CH3COOH with 0.55 M KOH. Determine the molar mass of an ideal gas B if 0.622 g sample of gas B occupies a volume of 300 mL at 35 °C and 1.038 atm.? In this case, chemical reactions within the water heater may be the source of the rotten egg odor. On the question as to how dangerous is H2S let me detail some facts that I find problematic.

Note, some sources actually disagreed on skin exposure poisoning of Hydrogen sulfide with one study alluring to skin toxicosis from high concentrations over a long period. If possible, it would be great to have two estimations: one of the beginning of the "danger zone", and one of the beginning of the "lethal zone". Now I'd like to do this experiment with my son, but in the meantime I learned that hydrogen sulfide is a very potent poison, even more poisonous than hydrocyanic acid. The gas can be smelled long before it starts to get dangerous, so I think it should be pretty easy to use an amount of sulfur and iron that will cause the characteristic smell, but at the same time is guaranteed to not cause any danger.
