Stripping chrome in an electrolytic bath

Aug 21, 2008 · arm that I needed stripping, and I got similar answers, that a plating shop would be the best bet as chrome plating, and the reverse electrolysis to remove it, would be rather hazardous. I was directed to a site similar to this called Caswell Plating, as I wanted to buy one of their chrome plating kits for my swinging arm, once I'd had it stripped.

4. Dip the copper strip and the object to be electroplated in the copper sulphate solution. 5. Electroplate for 20-25 minutes or till a uniform brown coating of copper metal is formed on the object. Electrolysis is used in the refining of impure metals. This method, called electrorefining, can be used to purify metals like copper, gold, and silver.

Electrolysis is a way to dissolve bits of metal into acidic liquids like vinegar. When you run electricity through vinegar, the vinegar helps to carry electricity from one side of the circuit to the other. Those bits of the vinegar react with the copper, making little bits of copper leave the positive side of the circuit and go into the liquid.
