A colloid is a size of particle.
Yes, I know something about colloids, and have used the settling test to determine the clay content of my garden soil; boots gain ten pounds easy, in winter. Brownian motion has fascinated me since watching my grandmother's cigarette smoke and the dust Sunday mornings in the sunbeams. She told me about the drunkard's walk too. <g> > > > All this will occur in water, tap water, that normally has other stuff > dissolved in the water as well. > > Now with getting silver to be ionically in solution requires that the > water be very pure and have nothing else in it, or else the silver will > react with whatever is there, and then you would have silver compounds. > So it is not really soluble in water, it is an artificial solution made > with specific parameters. I've actually gotten some dissolution of ionic silver, I think, into R.O. + de-ionized water, off the 'trodes with no electric current; not much, but a higher reading than I get from simply leaving the water in the jar exposed to the air. Perhaps the wire surface from previous electrolysis was pitted on a fine enough scale to encourage some dissolute ionic misbehavior. . . . . > > There are silver salts, like silver nitrate, which will dissolve in > water, but that is not what we are after.

Well, back to my original query which I didn't make clear: There are both ionic and co-valent I think they are called solutions, ionic like the classic example of table salt or covalent like sugar - or to the limited degree it does so, ether; Alcohols, I dunno from. So my question was: having a solution of ionic silver already in hand - in jar - were you saying that any addition to the solution, whether an ionic or covalent compound, or an element, would cause the silver ions to regain neutral charge, precipitate out, be driven to hydroxide or whatever, and if that were the case, what would be their likely fate? OTOH, were you saying that in order to Make CS you need pure water, in which case I misunderstood your drift when you said, "The ionic silver is only in the water because there is nothing else in the water. ..." > > I hope this has helped some....
