A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge. 2Fe3+(aq)+Sn(s)2Fe2+(aq)+Sn2+(aq) The anode reaction is: ++ The cathode reaction is: ++ In the external circuit, electrons migrate the Fe2+Fe3+ electrode the SnSn2+ electrode. In the salt bridge, anions migrate the SnSn2+ compartment the Fe2+Fe3+ compartment. A voltaic cell is constructed in which the anode is a II2 half cell and the cathode is a Fe2+Fe3+ half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: The cathode reaction is: The net cell reaction is: + In the external circuit, electrons migrate the II2 electrode the Fe2+Fe3+ electrode. In the salt bridge, anions migrate the Fe2+Fe3+ compartment the II2 compartment
