Testing Faraday's law



(-----) 2006

Hi, I'm in grade 12 I was wanting to test Faraday's electrolysis law through electroplating something for example silver, with iron from an iron nail, using one amp. I would then weigh the nail a different time interval, and hopefully prove that time is proportional to mass. I just don't know where to start, I need help with designing this experiments and procedure!

Iron is very difficult to plate, Jaclyn, and its multiple oxidation states (ferric, ferrous) will wreck havoc on your experiment of proving Faraday's Law of Electrolysis. If you are willing to plate the silver with copper from a copper sulphate plating bath you'll make better progress. But I'd keep the plating rate quite low, like less than 5 Amps per square foot of surface area. Good luck. You'll probably want some copper wire for an anode. Good luck.
