Hypochlorous Acid Generator

[dik]

Does anyone have a quick discription of a DIY generator for Hypochlorous Acid. Should be easy to make... A matter of electrolysis of salt water. Create a good, cheap really useful disinfectant for Covid 19, I understand... from reading, it's not snake oil.

titanium forms a titanium oxide surface which is an insulator and stops the activity. They use a mixed metal oxide (MMO) coating to prevent the formation of titanium oxide, as I understand it.

You won't get any help from me, even if I knew how, with that type post.

Has there been any research into the use of daffodils as a possible delivery vehicle?

waross: HEheehehehehehe I remember that from decades back...

hokie: That was one suggested delivery method... and funnier than a rubber crutch. I wasn't looking for a delivery method... only production... but, I provided an answer to Bill's question. I always like providing answers...

hypochlorite generator

From the net... "They are very different! They have different chemical formulas; the formula for sodium hypochlorite is NaOCl & the formula for hypochlorous acid is HOCl. Hypochlorous acid is the same substance your white blood cells produce to fight infection. And it's so gentle it's used in wound healing products."

Hypochlorous acid (HOCl or HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO and ClO− are oxidizers, and the primary disinfection agents of chlorine solutions.[2] HClO cannot be isolated from these solutions due to rapid equilibration with its precursor. Sodium hypochlorite (NaClO) and calcium hypochlorite (Ca(ClO)2), are bleaches, deodorants, and disinfectants.

Hypochlorous acid was discovered in 1834 by the French chemist Antoine Jérôme Balard (1802–1876) by adding, to a flask of chlorine gas, a dilute suspension of mercury(II) oxide in water.[3] He also named the acid and its compounds.

(Balard, 1834), p. 293. From p. 293: "Quelle dénomination … appelées hypochlorites." (What name should one assign to this compound? It's obvious that that of "chlorous acid" can hardly be retained for it, and that it is more appropriate to call it hypochlorous acid, a name that recalls its similarity of composition with hyposulfurous acid, hypophosphorous acid, etc., [which are] formed, like it, from 1 equivalent of their radical and 1 equivalent of oxygen. Its compounds will be called hypochlorites.)

bimr: "With one fewer oxygen than the “-ate” ion, the acid will have the suffix “-ous.” For example, chlorous acid is HClO2. With two fewer oxygen than the “-ate” ion, the prefix will be “hypo-” and the suffix will be “-ous.” For example, instead of bromic acid, HBrO3, we have hypobromous acid, HBrO."

The solution is generated by the electrochemical activation of a brine solution of sodium chloride. The pH at which it is generated is between 6 and 7, ensuring that hypochlorous acid is the dominant species.

Yup... thanks.

One reason that they coat the Ti electrodes is to get higher efficiency.
After all the oxide coating are also non-conductive (they are actually semiconductors).
Many of the pool units don't bother with coatings.

Thanks, Ed... still going through 3DDave's link... some great, some not so great, but generally informative. Got busy again and have to take a bit of a break.
