I believe the solubility is low, >but between 10 and 20 ppm (which many chemists call insoluable). ## It happens after a good particle stream is running about in the water and contacts an obstruction such as the bottom of the container for a gooodly amount of time...probably only at over 10 PPM as under that , the water isn't conductive enough, nor are concentration zones around and between the electrodes in an "ion track" [My mis-use of a self coined term? ;-)] saturated enough to form or precipitate many particles of any kind. 'Ion tracking' might be a real term...but I still made it up. What's weird is that, when using lots of current and allowing "ion tracks" to form, golden particles cloud around one electrode, white ones around the other..and nothing in between unless something gets in the way. If something does get in the way, you get metallic silver plate out AND both colors of particle with a white spot and a black spot on either end. Reduce current and you only get the white ones. [This is my 'current' rule of thumb when deciding how much current to use] My 'guess' is that the white is silver hydroxide forming and the golden, some sort of silver oxide forming... both dissolving at the mid point and staying dissolved till some saturation point is reached either locally or thoughout. Then, metallic silver particulates? If current is low, I'm guessing that the oxides pretty much stay on the electrode and don't form in the water...no golden particles....colorless EIS at any PPM, unless some other contaminant starts playing the crystal nucleus role at some other varying point. Looping back around to the 'idea' of oxides playing a role in building crystal lattice structures making larger particles [with color due to size but not due to pigmentation from oxides] possible and susceptible to breaking apart with the addition of hydrogen peroxide later on...as hydrogen peroxide DOES discombobulate oxides on the black electrode and if used as part of the electrolyte, forms huge shiny silver snowflakes that eventually turn into black oxide balls...whereas and similar to...if an oxide black electrode, once cleaned and shined up by H2O2 is 'left' in H2O2, it turns black again. All that said, there may well be a few different acting forms of silver oxide involved at different times, under different conditions, in different places, doing different things. Whew! What things, when and how, goes too way far over my head to even guess at. All I 'know' is, it isn't at all simple...then ...it gets complicated.... even 'before' using the stuff in 'another' myrid of manners and combinations. Oh well, "plug and glug" works OK. We don't know what 'matter' is either, but we can still bonk ourselves on the head with it and believe it matters...taking an effect as proof that there's something there while looking closer reveals that nothing is. Proving that nothing really can put a dent in nothing other??? LOL The word paradox comes to mind.
