I was truly impressed. > Either way, I do know that CS is more aptly referred to as > 'electrically isolated silver.' Dunno why. Collodial silver is silver ions in solution, or cs for short. They all have some particulate content. You just happen to have a higher ratio than most:) 'Electrically isolated silver' doesn't say anything about the composition. Could be anything. Could be arcs drawn from silver electrodes in air. Colloidal silver has a long history of use. I don't see why people want to redefine the term. Unless they want to sell something. Then I get real suspicious of their motives. > So my question is this: if the great majority of silver in > solution is some compound (or the metal), what the heck is keeping > the particles electrically isolated?

One thing that might be going on is the high temperature you are running. The particles grow to the size that makes the red color. Then they are limited by the availability of fresh ions, and the thermal velocity which affects the diffusion rate. You also have considerable convection currents that probably outweigh the thermal velocity by a large factor. A very complex system indeed:) When the solution cools down, the reactions decrease immensely. I tried to find some information on the reaction rate with temperature, and came up with several different values. I think a rough rule of thumb for the Arrhenius model is that it doubles every 10C. Might be wrong on that - just from memory after a long day. If this holds true, when the solution cools down to room temperature, the reactions slow down by 2^7, or a factor of 128. So the particle interaction is greatly reduced, and maybe this explains why the solution is stable. Just a guess, of course. There's a lot of things going on with your system that have not been explored before. And a lot of interesting things to learn. Keep asking those great questions:) > Cheers, Reid Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
