How electroplating works Explain that Stuff

May 20, 2019 · Generally, one of the electrodes is made from the metal we''re trying to plate and the electrolyte is a solution of a salt of the same metal. So, for example, if we''re copper plating some brass, we need a copper electrode, a brass electrode, and a solution of a copperbased compound such as copper sulfate solution.
