Is hypochlorous acid stable?


Depending on the process used to generate the hypochlorous acid, the solution can be stable. Membrane cell electrolysis generates two streams with opposing oxidation-reduction potentials and opposite pH. This is done by forcing positively charged sodium ions across a membrane toward the cathode side. On the anode side, a very high concentration of anolyte is generated that is strongly acidic (~ pH 3). Generating hypochlorous acid by this method is not as stable as that generated by single cell technology. Single cell technology uses an acidified brine and only one stream of solution is generated in the pH range of 5-7. When generating hypochlorous acid through a single cell, no high pressures are used and no ions are forced across a membrane. The hypochlorous acid generated is stable, not seeking a new equilibrium like the anolyte generated from membrane cell systems.
