electrolysis Can every conductor be electroplated

2014-9-12  I really like electrolysis. Today I bought 30% sulphuric acid to electroplate something with pieces of copper. I've poured half water and half acid in a glass. I connected some cuprextit-copper plate to the anode and outdated aluminium coin to the cathode. After starting the process, I could see that nothing is appearing on the cathode.get price
