Basically, what will happen is that dissolved Ag+ will turn into silver metal on the surface of a more reactive metal. Saying that silver will "plate out" on most metal containers which are more reactive than silver is an oversimplification (I get the feeling I'm going to run out of answers before you run out of questions) because certain metals, such as stainless steel will "passivate" and become unreactive due to their tendency to form an impervious (mostly) metal oxide coating. I admire your enthusiasm to learn as much as possible, but before we bore too many folks who are less scientifically inclined, perhaps you could speed things up by telling us exactly what CS process application you have in mind.
