Lots of reading in that article. I didn't sleep much at all.
"Hypochlorous acid is widely used as a disinfectant, for example, in sanitizing wash solutions and swimming pools. In these applications, the reactive chemical is formed in solution by the addition of chlorine to water."
We have more testimony, from a completely different source, backing that simply chlorine + water = hypochlorous acid. There's even a reference to pool cleaners.
" At pH values greater than 5.5, hypochlorite ion (OCl−) is formed, and around pH 7.5 (the pKa of HOCl of the chlorine species in solution is at 50/50% mixture [HOCl/OCl−]). As the pH increases from 9.5, the concentration of OCl− in solution reaches its maximum level, becoming 100% hypochlorite (also referred to as bleach). However, on the acidic side at pH less than 4, the solution exists as a mixture of chlorine (Cl2) in aqueous phase, chlorine gas in the headspace, trichloride (Cl3−), and HOCl. At pH less than 3, an appreciable amount of Cl2 gas forms, which may cause the rapid loss of all active chlorine in an open container. To keep the solution stable and maintain its desired activity, the pH of the solution should remain between 5 and 5.5 and the solution should be stored in a tightly sealed container. For the first time, we have been able to determine these conditions to stabilize HOCl and to assess its biological properties as a pharmaceutical product."
The higher the ph (9-10) the more it turns to just bleach. At 7 ph the article states the mix is roughly 50% HOCl and 50% bleach. I plan to mix one solution at 5-5.5 and one at 7 and record any visual differences and test both solitons with a colorimeter or test strips. I plan to get those after work
