The CuCu ions undergo reduction by accepting two electrons from
the copper electrode (cathode) and depositing on the electrode as
Cu(s)Cu(s). The reduction half-cell reaction that takes place at
the cathode is
Cu^2+(aq)+2e^−→Cu(s)Cu^2+(aq)+2e^-→Cu(s)
The electrons lost by the ZnZn metal are gained by the CuCu ion.
The transfer of electrons between ZnZn metal and CuCu ions is made
possible by connecting the wire between the ZnZn electrode and the
CuCu electrode. Thus, in the voltaic cell, the electrons flow
through...
