Question

A voltaic cell is constructed in which the anode is a Fe|Fe2+ half cell and the cathode is a H2|H+ 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 (from or to?) the H2|H+ electrode (from or to?) the Fe|Fe2+ electrode.

In the salt bridge, anions migrate (from or to?) the Fe|Fe2+ compartment (from or to?) the H2|H+ compartment.
