Draw out a cell for Al in Al(NO3)3 and Ag in AgNO3. Label the anode and cathode sides, including charge on each electrode. (hint: use a table of standard reduction potentials). Indicate direction of electron flow. Write the net reaction, and the half reactions. What is the standard cell potential? Indicate for both electrodes whether they are dissolving, growing, or staying the same size. Assuming the salt bridge contains KNO3, indicate flow of ions into and out of salt bridge....

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...
