Hi Ivan et al, If the silver "ion" has a positive charge, which is a "valence", and it gets an electron from an electrode, why does it not just keep it?

If this what you mean James :-) Yes we have a soup of water molecules, a very small amount of which are ionised into OH- and H+, plus impurities. However the clumps of silver atoms in the water have lost one or more electrons due to the electrolysis process, and so float around carrying an electrostatic charge. When we dip a couple of electrodes in the solution and apply a potential difference (generally an 10kHZ AC signal to avoid electrolysing the sample) the charged particles are caused to move towards the electrodes, and their ability to accept electrons or donate electrons allows a current to flow in the meter, blah, blah, blah. I should think the impurities in the water probably far outweigh the impurities in silver electrodes .999 or higher.
