An electrochemical cell consists of two silver electrodes placed in aqueous solution of silver nitrate. The positive electrode is called anode, whereas the negative electrode is called cathode. A constant current of 0.5 A is passed through the cell for 1 hour. a) What is the total charge q transported through the cell? b) If one electron is needed to discharge one positively charged silver ion (that is, to neutralize the ion and deposit it on the cathode), how many...

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...
