How to Do Silver Plating Sciencing

13/03/2018· The terminal is commonly red and identified with a plus sign. Connect an alligator clip to the other end of the wire and clip it onto a piece of silver, which will serve as the source metal for the plating process. The silver, attached to the battery, is known as an anode. Slowly lower the anode into the electrolytic solution.

Electrolysis and Electroplating Definition, Working

A piece of silver is connected to the positive terminal. The electrolyte is a silver nitrate solution. This process can also be used to purify silver. We can take an impure block at the positive terminal and a strip of pure silver to the negative. The pure silver is deposited via electrolysis at the negative terminal leaving behind the impurities.
