In a copper-zinc voltaic cell, one half-cell consists of a ZnZn
electrode inserted in a solution of zinc sulfate and the other
half-cell consists of a CuCu electrode inserted in a copper sulfate
solution. These two half-cells are separated by a salt bridge.
At the zinc electrode (anode), ZnZn metal undergoes oxidation by
losing two electrons and enters the solution as Zn2+Zn2+ ions. The
oxidation half-cell reaction that takes place at the anode is
Zn(s)→Zn2+(aq)+2e−Zn(s)→Zn2+(aq)+2e−
The CuCu ions undergo reduction...

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...
