what is electrolysis and what is the overall reaction in this
experiment? write out the half reactions occurring at each
electrode (assuming you are electroplating copper.
Electroplating is the process by which a thin layer of metal is deposited on an electrically conducting surface. In electroplating, the metal to be plated is used as the anode and the electrolytic solution contains an ion derived from that metal. In this experiment, the copper electrode will be used in a solution of...
