The electrochemical cell which will involve the given cell reaction is depicted as Zn(s) | Zn2+(aq) || Ag+(aq) | Ag(s).
1. In this cell, the electrode Zn(s) | Zn2+(aq) will act as negative terminal and Ag | Ag+(aq) electrode will act as positive terminal.
2. The conventional current will ow from silver to zinc electrode in the external circuit.
3. Individual reaction at each electrode :
- Cathodic reaction : 2Ag+(aq) + 2e → 2Ag(s)
- Anodic reaction : Zn(s) → Zn2+(aq) + 2e-
