Hello Marshall, It has been a couple of days now, and there is some silver that is now covering the bottom of my bottle.
I added some baking soda to the solution and brought the PH up to 6.7. The ORP now reads around 20. I believe the earlier reading was around 186, so there seems to be some relationship to PH. While 20 is not quite 0, it is pretty close, and I am still a little acidic with the solution. The amount of silver on the bottom of the bottle looks to be about the same as was observed in the other bottle.
