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/[email protected]/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.
