It wouldn't be pure dithionite, other wise it wouldn't work at all for ammonia. Sodium thiolsulfate is really not stable it undergoes autocatalytic oxidation process. I agree really pure fresh samples are clear, but if left out or exposed to ph changes usually turn to yellow. A lot of samples are contaminated with polysulfides. Its part of one of the ways its made. Look at api conditioner for example, that does have thiolsulfate, and it is yellow tinted. Chances are they would not use it if it had a long shelf life. That could give a clue that if is not used in there. Another thing that would make thiolsulfate useless. If it is in there it is one of the ingredients that break chloramines. The bisulfite will also. Plus "
"Dithionite undergoes acid hydrolytic disproportionation to thiosulfate and bisulfite:[2]
2 S2O2−4 + H2O → S2O2−3 + 2 HSO−3
It also undergoes alkaline hydrolytic disproportionation to sulfite and sulfide:[2]
3 Na2S2O4 + 6 NaOH → 5 Na2SO3 + Na2S + 3 H2O"
Thiolsulfate is a reducer. If this is a strong enough reducer. Reduced ammonia is amide. Which would still test out on ammonia /ammonium kit and like I believe the seneye. Probably not on nitrite kit. In the case of nitrite you would need an oxidizer for it to not read on nitrite kit . Hense bifulfite.
I give you some examples of real ways to test yours. My nose and nerve endings are pretty accurate lol. I wont disagree that it is the best way to test melting points. One would actually need the proper machine which cost a ridiculous amount. Cant really do this reliably with most thermometers. Your taking thread out of context. Yes challenge the idea please. Vinylsulfonic acid alone is toxic to a degree. Not as toxic as ammonia. It also acts to bind with it making the more evil of the two not as toxic as well as itself. Again this is why you see tests building up levels when used indicating it is in there. Not to mention the myriad of things it can react with. The bound ammonia slowly getting into blood stream is what is doing. Then in here it reacts with other things in the body you see? Electrolytes, other amines, the blood itself, and others etc...
