with a solution in them connected by a liquid salt bridge junction filled with KNO3. In one solution you have a graphite electrode that is connected with a wire to a copper electrode in the second soution. The soution in contact with the graphite electrode consists of dissolved Sn(NO3)2. The solution in contact with the copper electrode consists of dissolved CuNO3.
a) write the standard half cell reduction reaction equation for each solution?
b) what are the standard half cell potentials; E anode and E cathode?
c) If the electrochemical cell is allowed to operate as a gavanic cell, which solution species will be oxidized, which solution species will reduce?
d) write the sybolic representation for the galvanic cell.
e) what would "standard conditions" for this galvanic cell be?
f) If the cell is at standard conditions, determine the cell potential(E cell).
