A voltaic cell is constructed in which the anode is a Fe2+|Fe3+ half cell and the cathode is a Br-|Br2 half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.)
The anode reaction is:
(aq)(s)(l)(g) + (aq)(s)(l)(g) > (aq)(s)(l)(g) + (aq)(s)(l)(g)
The cathode reaction is:
(aq)(s)(l)(g) + (aq)(s)(l)(g) > (aq)(s)(l)(g) + (aq)(s)(l)(g)
The net cell reaction is:
(aq)(s)(l)(g) + (aq)(s)(l)(g) > (aq)(s)(l)(g) + (aq)(s)(l)(g)
In the external circuit, electrons migrate (from/to) the Fe2+|Fe3+ electrode (from/to) the Br-|Br2 electrode.
In the salt bridge, anions migrate (from/to) the Br-|Br2 compartment (from/to) the Fe2+|Fe3+ compartment.
