How bad are nitrogen and sulfur based acids? Is it worth using it in water for the ozone?
These are primarily nitric and sulfuric acids, but they are not a major problem in the tiny amounts formed. More minor irritants to the tissues. If ozonating water though a simple way to deal with these is to use spring water or if the water is distilled or reverse osmosis just add a pinch of calcium carbonate (oyster shell, dolomite, coral, etc.) or magnesium oxide. Any of these will neutralize the acids.
