Fundamental question.
Where is the *sulphur* coming from that makes the silver "tarnish" to start
with ?
AgOH [Silver Hydroxide] isn't black..it's whitish to tan. [look it up]
AgO is formed when oxygen encounters a silver ion...and it is yellowish, to
brown, to black depending on how dense the concentration of the pigment.
Oxygen gas is produced by electrolysis, as is Hydrogen gas.
We do see Hydrogen bubbles.
Why do we never see Oxygen bubbles? The Oxygen probably makes Silver
Oxides out of some of the silver ions before they even form, ya think?
There are several configurations of silver oxides, either destroyed or
made by exposure to H2O2.
One of them is a byproduct of electrolysis.
H2O2 will clean up a black electrode in just a few minutes, then turn it
black again in several more, indicating 2 different forms of silver oxides
Equations don't change the eyeballs, but I suppose they can lead to tunnel
vision.
Add in elements that aren't there [Sulphur?] or leave out a few that
are...and equations can be made to prove any thing you want them to.

Ode,
1. We do not want to immerse the electrodes in a sodium solution. It
will be very difficult to remove the ions.
2. The galvanic series shows the electromotive force when different
metals are immersed in an electrolyte. One example is
http://www.ssina.com/corrosion/galvanic.html
This shows aluminum is positive with respect to silver. This means
we can eliminate the sodium ions and use our own dc supply to
accomplish the same thing.
3. The classical equations show that the sulfur is deposited on the
aluminum. However, this produces aluminum sulfide, which decomposes
in water. Please see
http://en.wikipedia.org/wiki/Aluminium_sulfide
In distilled water, the classical equations are incorrect or do not
apply.
4. Instead of aluminum, you could use copper or zinc as the anode.
However, metals other than aluminum release ions into the solution,
which would travel to the silver cathodes and contaminate them.
5. The typical equations posted on the web are incorrect. They
contain many fundamental flaws, such as mass and charge inbalance in
the coefficients, and gross errors such as stating the sulfur ion is
positive. It is not. The sulfur ion is S(2-), not S(2+)
6. Aluminum is inert in this reaction. I have posted the correct
equations to my Yahoo forum at
http://health.groups.yahoo.com/group/silvercentral/message/20?l=1
I made one small error. It is corrected at
http://health.groups.yahoo.com/group/silvercentral/message/21?l=1
7. The black stuff that forms on the electrodes is silver hydroxide,
AgOH, not silver oxide, Ag2O.
Your statement is incorrect.
You cannot produce silver Oxide, Ag2O, by using electrolysis.
8. Every silver surface tarnishes. You cannot wipe it off. The film
is invisible at the beginning, but it will severely impact the
brewing process, and cause a significant reduction in the silver ion
concentration in the 48 hours following the brew.
9. The reduction in ion concentration severly reduces the
effectiveness of the colloidal silver. You may examine my post to
sol to verify this:
http://www.mail-archive.com/silver-list@eskimo.com/msg76134.html
Please note that sol also remarked that a weak solution did not work
as well.
You cannot remove the silver tarnish without damaging the
electrodes, except by the process I have described.
When you do, you may find your brew is much stronger than before,
and much more effective.
However, for the ultimate in colloidal silver generation, please
visit my forum at
http://health.groups.yahoo.com/group/silvercentral/messages
Here you will find the most significant advance in colloidal silver
generators since the original 3 nines.
