Question: A voltaic cell is created using silver (Ag / Ag + ) as one electrode and manganese (Mn / Mn 2+ ) as the other
A voltaic cell is created using silver (Ag / Ag+) as one electrode and manganese (Mn / Mn 2+) as the other electrode.
| Reduction half-reaction | Eo (V) |
| Ag+ (aq) + e- ⟶ Ag (s) | 0.80 |
| Mn2+ (aq) + 2 e- ⟶Mn (s) | -1.18 |
a) which metal is the anode and which is the cathode?
b) write a balanced chemical equation for the redox reaction occurring in the cell.
c) draw a diagram of the cell. Be sure to label the cathode, the anode, Ag, Mn, Ag+, Mn2+, the direction of electron flow, and the direction of cation and anion flow from the salt bridge.
d) what is the potential of this cell when the Ag+ concentration is 0.045 M and the Mn2+ concentration is 1.67 M?
