What is the relationship of Salt, White Vinegar, and Water to create 1 liter of Hypochlorous Acid (for disinfecting and cleaning purposes), and how much time do I have to put it under a 9v battery induced electrolyzing process?

  • $\begingroup$ Vinegar and water do not make any chemical reaction. So they will not produce Hypochlorous acid. If you want to produce hypochlorous acid, you have to electrolyze salt alone, without vinegar. The main point is not the tension (9 V), but it is the currant. And the currant depends upon the geometry : surface of electrodes, distance between electrodes and resistance of the solution. The duration of the electrolysis may be many hours. But it depends on the currant. Vinegar may be added at the end of the electrolysis. $\endgroup$ – Maurice Mar 30 at 19:22
  • $\begingroup$ The vinegar is added to the salt solution to raise the pH to shift the product equilibrium from sodium hypochlorite to hypochloric acid $\endgroup$ – mpprogram6771 Mar 30 at 19:34

    $\begingroup$ Vinegar would lower the pH. $\endgroup$ – Ed V Mar 30 at 20:16
  • $\begingroup$ The action of a weak acid (even H2CO3, acetic acid, Vitamin C,...) are generally all stronger than HOCl and will displaced it from NaOCl. Best preparation reaction is CaCl2 + NaOCl (Chlorine Bleach) + NaHCO3 (Baking Soda) creating HOCl, a precipitate of CaCO3 and Na+, Cl+ ions. Decant to separate out the CaCO3. Best stored cold and used within a day or two. Unstable, Cl2, Cl2O fumes... $\endgroup$ – AJKOER Mar 31 at 0:57
