Question

A voltaic cell is constructed in which the anode is a Cr|Cr3+ half cell and the cathode is a F-|F2 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 Cr|Cr3+ electrode 

 

 the F-|F2 electrode.

In the salt bridge, anions migrate 

 

 the Cr|Cr3+ compartment 

 

 the F-|F2 compartment.
