A voltaic cell is constructed in which the anode is a Cd | Cd2+ half cell and the cathode is a Ni Ni2+ half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Be sure 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 In the salt bridge, anions migrate + + Enter electrons as e. + the Cd|Cd²+ electrode the Ni Ni2+ compartment | ✓the Ni Ni2+ electrode. the Cd | Cd²+ compartment.
