A voltaic cell is constructed in which the anode is a Mg|Mg^2+ half cell and the cathode is a Zn|Zn^2+ half cell. The half-cell compartments are connected by a salt bridge.
(Use the lowest possible coefficients. Use the pull-down boxes 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 Mg|Mg2+ electrode ____ the Zn|Zn^2+ electrode.
In the salt bridge, anions migrate ____ the Mg|Mg2+ compartment ____ the Zn|Zn^2+ compartment.
