I've been making solutions of silver ions by hooking 20-30V up to 2 silver electrodes in distilled water and noticed something interesting. The solution starts off as clear and by adding a bit of NaCl, AgCl precipitates out so there's definitely Ag+ ions in there. If I leave the solution for a few days it turns amber coloured. This is the colour
whats going on here? I haven't bothered to retest for Ag+ ions but the only theory I've come up with is that the Ag+ ions have been reduced somehow and neutral Ag atoms absorb some light.
