Identify the cathode and anode in the cell written below.

Cu | Cu2+ || Cl– | Cl2 , Pt


Write the reduction half reaction and oxidation half reaction of the cell.


The cathode and anode are separated by a salt bridge. Anode is represented by the first half and cathode by the second one.


ANODE: Cu to Cu2+


CATHODE: Cl- to Cl2


REDUCTION HALF REACTION: Cl- + 2e-→ Cl2


OXIDATION HALF REACTION: Cu → Cu2+ + 2e-
