My theory is the silver ions form an invisible cloud around both electrodes. At the anode, they have just left and are slowly moving towards the cathode. When they reach the cathode, they form another cloud since hydrogen is also formed at the cathode, and there are no more electrons available to interact with. The density of these clouds is directly related to the current and voltage across the cell. At the anode, high current means a higher density of ions in the immediate vicinity of the electrode. This increases the chance that Brownian motion will push ions together until they get close enough for the van Der Walls effect to make them stick. Note the term "Brownian motion" is not exactly correct, but it is good enough for our purposes. Similarly, there are a number of effects that together form the van Der Walls force, and which one operates depends on the type of ion. It is OK to use van Der Walls to describe any of these effects since they are all lumped together. The same effect occurs at the cathode. When the ion cloud is dense enough, the particles become large enough to see, and form a mist. Usually, the mist first starts forming at the cathode. With low current, round wires and no stirring, it forms a uniform cloud about 1/16" thick around the wire. The cloud is denser than the surrounding water, so it begins slowly falling to the bottom of the glass. It may form a stream and go out at right angles to the rod, then disperse. The mist starts forming at the anode after it has already begun at the cathode. I believe the reason for this is the field gradient moves the ions away from the anode and towards the cathode, so the density is greater at the cathode. The proof is to reverse the voltage applied to the rods. The cloud that formed around the cathode disperses quickly without forming a stream. It simply disappears. I believe stirring has the same effect. The particles still form, but they are quickly dispersed. I believe this is why the three methods of stirring I tried produced cs that was not very effective. Running at very low current reduces the density of the ion cloud. This reduces the number of ions that are pushed together, and the mist doesn't form until you reach very high concentrations. This stuff is unsuitable for drinking - it has a very strong metallic taste and gives me an upset stomach. But it is OK to hold in the mouth for ten minutes, then spit out. My current approach is to run 6 hrs at 335 uA with 3.85 sq. in. wetted area and 425 ml of dw. This produces 7.24 Coulombs and 19 ppm calculated. The current density is 87 uA/sq. in. The rods stay clean with only a trace of black stuff after wiping. The salt test is quite strong. You can definitely tell it is having an effect after holding it in the mouth. Just run your tongue along your teeth afterwards. The teeth feel slightly rough and bits of tartar may fall off over the next few days. You may find small cavities you never knew about. But if you have a sore throat from a flu just starting, it will be gone the next day. Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
