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...
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...
