A voltaic cell is constructed in which the anode is a Ni|Ni^2+ half cell and the cathode is a Sn|Sn^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 net cell reaction is:
