1.

Depict the galvanic cell in which the reaction Zn(s) + 2Ag+(aq) → Zn2+ + 2Ag(s) takes place. Further show :1. Which of the electrodes is negatively charged?2. The carriers of current in the cell.3. Individual reaction at each electrode.

Answer»

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 flow 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-
