A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge. F2(g) + 2I-(aq) 2F-(aq) + I2(s)

The anode reaction is: + +
The cathode reaction is: + +
In the external circuit, electrons migrate the F-|F2 electrode the I-|I2 electrode. In the salt bridge, anions migrate the F-|F2 compartment the I-|I2 compartment.
