WebAnswer (1 of 2): The answer by Mr. Merlo is incorrect. I can indeed balance the reaction: 2H2O + K2S = H2S + 2KOH The answer has to do with acid/base strength. This is an acid-base reaction and K2S is acting as a base and H2O is acting as an acid. In both cases you are simply exchanging H from ... Webozone is required to produce sulfate from hydrogen sulfide than is required to produce sulfur. The theoretical dose to oxidize ozone to sulfate is 3:1, but in practice the ratio is 4:1. This will leave a small ozone residual in the water, 0.2-0.3 ppm. This residual can be used to ensure that the hydrogen sulfide is fully removed.
