Although the below statement is true, in that everything that comes
off those electrodes is ions, some colloid is produced when ions
convert to metallic silver with the addition of an electron to the
ion -after- it leaves the electrode.
Other colloidal particles are made as well...mostly silver hydroxide
and some silver oxides.
There is no question that silver ions kill germs or that ions present
the largest possible surface area.
There is no smaller "particle" possible.

Ode, What do you mean when you say that ions present the largest
possible surface area? How big is an ion? How big of a surface area
are you talking about? Are all ions the same size?
Thanks.

Hi Faith,
I am not Ode, but I can tell you that an ion is one atom of anything.
One single atom.
Now some atoms are larger than others, so some ions are larger than
others. For example, hydrogen may be the smallest, atomic weight of 1,
and uranium has got to be many ties larger, judging by it's atomic
weight, which is in the hundreds, I can't remember exactly.
Surface area relates to particle size like this: if you measure the
outer sphere of a ball, it is X square cms. or feet or whatever. If
you break that sphere into many smaller spheres, and measure each of
those and add it up, it adds up to a much greater number than the
original large sphere by itself.
There is a more important issue here, which is that an ion wants be
neutral. It is not, it has an electric charge, but it wants to not have
a charge, so it goes around waiting to run into something it can bond
with. That is why it is so vital to have very pure water to start with
when making CS, which is actually EIS. If the water is not pure, the
silver ions will bond with anything it can.
As far as actual size, I think it is way less than microns, it is more
like billionths of a meter? I am not sure, I would have to look it up.
However, this is all from our basic chemistry classes in college. Laws
of physics, etc.
