The other day I was at the store looking at some metal wall plates for light switches, they had all sorts of different types, Copper, Nickel, Stainless Steel, Chrome, …and “Brass plated stamped steel”. How can it be possible to electroplate Brass onto something? I understand how you can plate Copper or Tin or Silver, …., onto an object through the electrolysis of some solution containing those ions….but Brass? Brass is not a pure metal; it is a mixture of Copper and Zinc. You cannot make a solution of Brass ions, only a solution of Copper and Zinc ions and then when you go to plate it out, shouldn’t it electroplate out as Copper metal and/or Zinc metal based on the Standard reduction potentials of the two elements? The standard reduction potential of the Cu +2 ion to Copper metal is +.34 volts. The standard reduction potential of Zn+2 ion to Zinc metal is -.76 volts. These two values are a full 1.1 volts apart from each other, how can you plate them out together as Brass?
