Depict the galvanic cell in which the cell reaction is Cu + 2Ag+→ 2Ag + Cu2+
Oxidation takes place at the anode and reduction takes place at the cathode.
Anode- Oxidation half-cell: Cu → Cu2+ + 2e-
Cathode- Reduction half-cell: 2Ag+ + 2e- →2Ag
Overall reaction : Cu + 2Ag+→ Cu2+ + 2Ag
By convention while representing a galvanic cell, the following steps have to be followed:
1) The anode is always placed to the left and cathode to the right
2) The metal and electrolyte of the same half-cell are separated by a vertical line
3) A double vertical line which represents the salt bridge is placed in between the two half-cells to complete the notation of the galvanic cell.
Galvanic cell notation: Cu(s)| Cu2+(aq)|| Ag+(aq)| Ag(s)
