Re: Aquatic Plants Digest V3 #684

Hello Paul,

You are absolutely right, that electrolysis of water can produce only
oxygen and hydrogen. The oxygen, however, in its *nascent* state (i.e.
probably O.), can react with carbon. Now the big question is whether the
product will be *only* CO2, or whether some CO will be also produced?

Maybe the toxic effects observed by Roxanne are due to CO produced
primarily in the beginning of the electrode's life cycle, until the
carbon electrode "runs in"? Or are there some compounds used in
preparation of the electrode that are toxic, but with time leach out?

Anyway, electrolytic CO2 is a nifty idea that seems to work for some
people. I wonder whether satisfaction is manufacturer dependent? Or is
there only one manufacturer?
