TinMan's "Over Faraday HV HHO production"

[Cherryman]

Lead is an interesting anode. It initially makes no oxygen as it forms a layer of oxide. This oxide is special as it conducts unlike other oxides and only forms a thin adhesive layer. Eventually oxygen  begins bubbling. The lead seems to last for ever, unlike stainless which often oxidises under heavy currents forming a  brown liquid probably full of toxic Cr 6+.
I can't remember the exact conditions but I managed to make ozone using lead electrodes in sodium carbonate solution with 20 or so volts. It came as quite a shock to smell the distinctive smell of ozone as at the time I did not know that ozone can be made by electrolysis of water.

Hmm I like it, lead is interesting...
They keep finding once in a while very ancient perfectly conserved bodies in lead coffins and a "special" fluid ..
It could be a conservational formula..  in more ways as one.
In our country lead is still considered as a good weather (long time) influence resistant material on roofs
In Alchemy it is a step-stone to gold * smile*
I do wonder if the oxidized layer has influence in production.[/size]


Would it be coïncedential if it would "lead"the way ?

A few weeks later s colleague needed to test some ozone detectors and I proubly mentioned that I could generate some for him without using sparks. I had packed up my electrolysis experiment by then so I used some stainless I had laying around. This time I was embarrassed as the same volts and carbonate failed to make any ozone. I figured the lead oxide electrode is a requirement for ozone production. Its easy enough for anyone to replicate, the voltage was between 20 to 30v, electrodes were lead strips about 1/4 to 1/2 inch wide and solution was DI water with enough carbonate to give plenty of bubbles but not too much as to lower the voltage required. Bicarb could work, otherwise boil the bicarb solution as it turns into carbonate in just a few mins.

Any updates on this investigation, its been months.

Not ozone because the ozone gas(O3) only forms at high voltages on the ambient air.But seems like Chlorine(CI) which is used in the bleach.

Hi pomodoro,here is also a quote from wikipedia;"Ozone's odour is sharp, reminiscent of chlorine".
