Well, actually I do believe that they are aggregating, then breaking
apart again when you dilute. You must have missed my post on a theory
as to how that happens when I posted it a month or so ago. Here it is
again:
As the water evaporates the silver oxide reaches saturation, and
precipitates out. These precipitated molecules have an affinity for the
silver particles and thus stick to them which then provides a site for
another particle to stick to, thus we end up with particles stuck
together with silver oxide as the mortar. So the particles grow larger,
but are really like popcorn balls, where the popcorn is the original
silver particles, and the candy is the silver oxide. Now since the
particles are indeed larger they will end up absorbing light toward the
longer wavelengths, just like silver particles without the oxide do, and
thus will make the expected color changes. But when you dilute back
with distilled water, the content of dissolved silver oxide drops below
the saturation point, and the silver oxide "glue" holding the bunch of
small particles together dissolves, and they fall apart, returning to
like they were before the solution was concentrated.

The reducing was my post and I didn't say anything about boiling the
cs, only putting it on the coffee maker hot plate which will not boil
it. It will steam off slowly and not effect the integrity of the brew.
You were into color being caused by the size of the particle at the
time and I disproved that theory by adding the exact amount of water
removed and having it turn back clear. There would be no way that
adding the distilled water back in could break the agglomerated silver
back into ions. I'm not very smart but that would be my take on it.

So Marshall and all you other experts, let me double check
with you about
the high voltage arcing -- you are sure that it will produce
silver nitrate?
Yes, especially if the arcing is above the water. using arcs to
water was the standard method of producing nitric acid during
WWII. Once you produce nitric acid, any silver going into the
water will immediately become silver nitrate.
Or perhaps can it also be producing silver ions with extra
oxygen? (I know,
wishful thinking).
That is a possibility, have not explored that. However if it did
it would precipitate out. The Silver Oxide that we produce that i
AgO has a solubility of about .8 ppm. Silver peroxide AgO2 is
totally insoluble.
I'm just thinking that I used whatever that produced for
several years, and
it worked great for preventing illness. Only trouble is the
beginnings of
argyria in my wife, and blue moons in me.
Yes, with silver nitrate I would expect that. Silver nitrate is
the least stable form of silver that I know of that does not
explode when touched. It is also very photo sensitive. It is not
generally used in photography because of its high solubility, and
lack of stability, reverting back to silver too easily.
I guess I'm looking for something to improve on 15-20 ppm low
voltage EIS. The reason is that since I went to that a couple
of months ago, I have
gotten a cold, albeit a mild one, and my wife got that food
poisoning after
stopping EIS for one week. And we have both noticed that the
low voltage EIS
does not last very long when we use it for deodorant. The
arced stuff, and the
silver citrate I just made seem to last 24 hours easily,
which makes me
think they are much stronger.
Try adding some H2O2 to it, maybe 3-4 drops per 8 oz glass, and
let sit for 5 minutes or so.
Isn't there any way to make a strong EIS without risking
argyria? Or is
that the tradeoff?
The only way to exceed the 20 ppm is to make silver salts instead
of EIS, which all will cause argyria. Actually there IS one way
according to some postings on here a month or so ago. Supposedly
you can slowly boil EIS down to a higher ppm withour it
precipitating out, apparently the silver oxide/hydroxide will
convert to colloidal and not fall out, but I have never tried it.
How about H2O2? I haven't really tried that one yet. That
will be next, I
guess.
For some experiments run long ago and reported here, H2O2 appeared
to improve the effectiveness of EIS by from 5:1 to 10:1 if I
remember right.
