Thanks for sharing.. There was a hole in my memories of fourth grade science. I do however, remember, that the point of any experiment , was a scientific method. Did you also know, that if you stick your fingers in your ears - it becomes really hard to hear? Just another miracle of science... Base/acid - fingers/ears.. same thing You can prove this by putting your fingers in another person's ears. Eventually, (and hopefully) this "list" will recognize the the maximum effacy of suspended silver solutions is in the charge of the solution. I don't read all the tripe, but I have yet to see any reference to an electroscope. Like it or not folks, finely divided silver IS sensitive to light. Internally, ANY silver is better than NO silver. CS as you refer to it, is not a colloid at all. Any silver particle in a suspension of pure H2o is heavier than the suspending medium. In lay terms, a true colloid would be a jar full of pink fish eggs. If one were to pick a few eggs, inject them with a blue color and a grain of sand to make them heavier than the rest, and put them back, - that would be a true colloid. They would stay in apparent suspension. even though they were heavier ( because of the sand), because the slight increase in weight is not enough to displace pink fish eggs around them. If the container were vibrated, they would eventually reach the bottom. Gravity rules. Very fine suspensions of silver will all eventually settle out. The silver particles bump into water molecules, like bumpers on a pinball machine. The smaller the particles, the longer it takes. It will happen eventually. If the silver particles have like charges however, they will continually repel each other, or "swim". As long as they remain charged, they are viable "swimmers". The nature of things is that all charged "things" seek equilibrium. Equilibrium can be reached by giving up a charge, to reach stability. If a photon (light), strikes a particle, that impact is sufficient to change (or in this case nullify) a positive charge on a silver particle. At that point, it becomes just a hunk of silver. Everyone in this group should be familiar with the mechanics of oxidation. In many ways, what I have seen in this group is exactly akin to worming your dog. You eat enough to kill ( or slow down ) the offender, but not enough to kill the host. Which, is fine. Your immune system needs all the help it can get. You would all do well to test the charge of your "solutions". -- The silver-list is a moderated forum for discussion of colloidal silver.
