Dissolving metals with silver ions

Silvers pretty far down in the activity series so would I be right in assuming I could dissolve a wide range of metals with silver ions? Silver ions are easy to produce, I just run some current through a glass of distilled water with silver electrodes. To verify that there are silver cations present I just add a bit of NaCl and look for AgCl precipitate. I'd opt for gold but silver is dirt cheap in comparison.

Maybe you could silver plate things this way, but I think the surface of the metal you'd be trying to dissolve would quickly become passivated by the layer of silver.

Good point. Silver electroplating would be fairly cool. Elemental silver has antibiotic properties so electroplating forks and knives wouldn't be a bad idea.
