What I have envisioned is 2 separate containers, each with its own
spigot,connected by a plastic valve. The 2 1/2 gallon water containers
available at grocery stores would be inexpensive, readily available, and
comes with its own spigot. A PVC type valve can be rigged with some
imagination to join them. As to the minerals in the water, I figured
some concoction to be used as an additive would give the ideal
separation qualities needed. As to the electrodes, my first thought was
to take powerful ceramic magnets and face them with poles opposite (
north to one container and south to the other ) . A litmus test would
tell if there were acid and alkaline, in which case simply closing the
valve would separate them from each other. After playing around with
gold and trying to make CG in the same manner as CS is generated, which
proved to be unproductive. It is my estimation that using gold terminals
would introduce the needed electrical current and be relatively, if not
completely nonreactive. Comments anyone?

Not by much. Alkaline water requires alkaline minerals to be
present to which one or more OH- ions attach.

The grey colour is elemental silver powder which origonate from
the dark electrode (anode, positive) as silver ions (Ag+), travel
through the solution and find themselves at the cathode (negative
electrode), aquire an electron and become elemental silver (Ag).
The dark coating of the anode is probably due to the
disassociation of silver ions from the silver metal.

Quite low voltage is suspect as hydrogen gas will be formed at
about 0.5V and oxygen gas at about 1.6V. Generally water ionisers
only cause the migration of elements or minerals to the electrode
of opposite sign, so the alkaline minerals, having a positive
charge migrate to the negative electrode, bringing their
associated OH- water ions with them. It is the OH- ions which
render the water alkaline.

Yes, anything that alows ions to pass, but not water molecules.
Porous ceramics are quite often used.

I guess there is no reason why silver electrodes cannot be used,
except that silver ions will be generated at any voltage above
0.8V and silver compounds (ie. silver cloride) also. This is
probably safer than using stainless steel electrodes. Most
ionisers use platinum or paladium coated electrodes or graphite
electrodes.
