voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge. 2Fe3+(aq) + Ni(s) 2Fe2+(aq) + Ni2+(aq) The anode reaction is: + +
A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge.
2Fe3+(aq) + Ni(s) 2Fe2+(aq) + Ni2+(aq)
The anode reaction is:
| + | + |
The cathode reaction is:
| + | + |
In the external circuit, electrons migrate the Ni|Ni2+ electrode the Fe2+|Fe3+ electrode.
In the salt bridge, anions migrate the Ni|Ni2+ compartment the Fe2+|Fe3+ compartment.
