A voltaic cell is constructed in which the anode is a Cr2+|Cr3+ half cell and the cathode is a Ag|Ag+ 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:

__(aq)(s)(l)(g) + __(aq)(s)(l)(g) -----> __(aq)(s)(l)(g) + __(aq)(s)(l)(g)



The cathode reaction is:

__(aq)(s)(l)(g) + __ (aq)(s)(l)(g) ----->   __(aq)(s)(l)(g) + __(aq)(s)(l)(g)



The net cell reaction is:

__(aq)(s)(l)(g) + __(aq)(s)(l)(g) ----->   __(aq)(s)(l)(g) + __(aq)(s)(l)(g)



In the external circuit, electrons migrate _____(from)(to) the Ag|Ag+ electrode _____(from)(to) the Cr2+|Cr3+ electrode.

In the salt bridge, anions migrate _____(from)(to) the Ag|Ag+ compartment _____(from)(to) the Cr2+|Cr3+ compartment.
