Watering with soft water
That chemical reaction is no where in my message.
H2S is a byproduct of anaerobic digestion of organic material, and goes into water as hydrogen sulfide. "hydrogen sulfide is weakly acidic, dissociating in aqueous solution into hydrogen cations H+ and the hydrosulfide anion HS-: H2S ? HS- + H+ Ka = 1.3×10-7 mol/L; pKa = 6.89" "In the management of water-supply wells, iron bacteria are bacteria that derive the energy they need to live and multiply by oxidizing dissolved ferrous iron (or the less frequently available manganese and aluminium). .....The proliferation of iron bacteria, in some way, increases the chance of sulfur bacteria infestation. Common effects of excess iron in water are a reddish-brown color, stained laundry and poor tasting coffee. An equally common but less well understood problem is infestation of water supplies with iron bacteria. Iron bacteria are a natural part of the environment in most parts of the world. These microorganisms combine dissolved iron or manganese with oxygen and use it to form rust-colored deposits. In the process, the bacteria produce a brown slime that builds up on well screens, pipes, and plumbing fixtures. Tastes and Odors - Iron bacteria often produce unpleasant tastes and odors commonly reported as: "swampy," "oily or petroleum," "cucumber," "sewage," "rotten vegetation," or "musty." The taste or odor may be more noticeable after the water has not been used for some time. Iron bacteria do not produce hydrogen sulfide, the "rotten egg" smell, but do create an environment where sulfur bacteria can grow and produce hydrogen sulfide." "The purple sulfur bacteria are a group of Proteobacteria capable of photosynthesis, collectively referred to as purple bacteria. They are anaerobic or microaerophilic, and are often found in hot springs or stagnant water. Unlike plants , algae, and cyanobacteria, they do not use water as their reducing agent, and so do not produce oxygen. Instead they use hydrogen sulfide, which is oxidized to produce granules of elemental sulfur. This in turn may be oxidized to form sulfuric acid." These bacteria are often sold to people to reduce the sludge in ponds and sewage systems. CO2 goes into water to make H2CO3, carbonic acid. Under pressure both are in solution like in a well. When pumped out of the well and pressure is released, the gases come out of solution. The simple test for both is pump out a 5 gallon bucket of water, take a pH test. aerate and after 24 hours test pH again. If the pH rises then the gases have come out of solution. If it is H2S, that can be smelled in very small amounts. See, just cant spontaneously combine chemical reactions.
