i have a CUSO4 electrolyte 1 Liter put into the solution one silver plated spoon conected to the(plus + wire) and a inox sheet conected to(minus - wire ).i run the electrolyse with 5V/10A.
questions???
1-on the inox is a white gas bubels?? what is that? is that SO2????
2-on the inox is a dark braun color sludge??? what is that? Ag or Cu?

after 20 minuts the silver is going up from the spoon in many pieces isnt disolved into the solution.the spoon is now red is look like copper.
i filter the silver ,wash it in water many time diluet some hno3 in des water and put the silver inside ,and heated but no way to dissolve the silver.

what is the problem why the silver didnt dissolve in HNO3????
