Enter electrons as e-.


A voltaic cell is constructed in which the anode is a Sn|Sn2+ half cell and the cathode is a Hg|Hg2+ half cell. The half-cell compartments are connected by a salt bridge.

(Use the lowest possible coefficients. Be sure to 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/to  the Sn|Sn2+ electrode _____fromto the Hg|Hg2+ electrode.

In the salt bridge, anions migrate _____fromto the Hg|Hg2+ compartment _____from/to  the Sn|Sn2+ compartment.
