A voltaic cell is constructed in which the anode is a Cr|Cr³* 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 v the Cr|Cr³* electrode | v the Fe2*|Fe3+ electrode. In the salt bridge, anions migrate|. v the Cr|Cr** compartment | the Fe2*|Fe³+ compartment. +
