Oh, nope. I see my mistake now. The current is 0.19 A. Theoretically speaking, with the right molar concentration, should it work? is there a better (simpler and safer) way? Tanks a lot again

hi I´m working on a personal project, surfing through the internet but I can´t get it done and would really appreciate any help. I´ve been trying to electroplate silver onto copper but I have failed because of the passivation on the silver (cathode). The best dissolution for this, I´ve found on the internet, is with AgCl (precipitate) and HNO3 (aq) as a result of mixing AgNO3 (four grams dissolved in 100 ml of soft water) and HCl (300 ml with a concentration of 28%), with the current of a 9 volt battery (the square ones). I´m quite certain that the nitric acid should stop the oxide layer on the silver but this isn´t happening. How can I stop the passivation? Should I add another compound or the problem is in the current intensity? I cleaned both pieces with specific commercial products to remove oxides and grease. Besides I treated the copper with sandpaper to make room for the silver layer. Thanks a lot.
