Hi George, Yes, I have a good quality glass pH meter...The final pH is the same as the pH of the starting water, between 6 and 7.
There may be some merit in your thoughts, although in my own case there is little water dissolution as I mostly keep to conservative parameters, which see the reduction overpotential of hydrogen higher than the reduction potential of silver. In other words, the energy required to eject silver ions from the anode is lower than the energy required to produce H2 gas at the cathode. The energy required to generate O2 at the anode is higher still. So it is more likely that H2 is generated before O2 and the pH will rise due to the surfeit in OH-. In HVAC arc systems perhaps AgO(H) is being generated, this is more likely at low pH than in neutral or basic pH this would perhaps lead to the formation of H3O+, not sure.
