I dunno it may just be. Iv never experianced concentrations like this ever before. This is way more concentrated then an ozone generator can put out. It could be useful at one time or another when dry Ozone would be needed but given the availability  of atmospheric oxygen I wouldn't use these means unless absolutely necessary.

Yeh Iv made a couple but never put them to any good use. Mine consisted of two coils of wire one on the inside of a PVC tube and one coil on the outside. Air was pumped into the the tube and lead out the other end. I had another PVC tube over that one so the air made a second pass over the outer coil before being discharged. Its kind of hard to visualize but ill make up a schematic to post so you can see what Im talking about. I just started playing with my OBITs again so I may just make another one and do a threed on it. I wish I had a better camera though because im also trying to make an arc furnace right now because..... well there just fucking cool.

from what I understood the impurities/buffers added to hardware store H2SO4 are so it doesn't eat through metal, so much.....
Although the standard for drain pipes today is PVC, I learned the hard way that many drain systems are still made of iron.
Despite the buffers, and the fact that I still hardly felt comfortable letting more than maybe 20 - 30ml drain into the ceramic sink EVER, a plumbing disaster eventually emerged.
A friend of mine honestly, like really, wanted to do some fancy sort of etching/plating, and was concerned about the buffers, so he went to every damn HorselesscarriageZone and the like, and found one in the city that had 50% H2SO4 for motorcycle batteries.  He said it was pure, which would make sence considering the application.....one would imagine anyway
