A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge.
2Ag^+(aq) + Cu(s) → 2Ag(s) + Cu^2+(aq)
In the external circuit, electrons migrate ____ the Ag|Ag^+ electrode ____ the Cu|Cu^2+ electrode.
In the salt bridge, anions migrate ____ the Cu|Cu^2+ compartment ____ the Ag|Ag^+ compartment.
