A voltaic cell is constructed in which the anode is a Mg|Mg2+ half cell and the cathode is a Cr2+|Cr3+ 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 _____fromto the Mg|Mg2+ electrode _____fromto the Cr2+|Cr3+ electrode.In the salt bridge, anions migrate _____fromto the Mg|Mg2+ compartment _____fromto the Cr2+|Cr3+ compartment.
