My Notes
A electrolytic cell similar to that shown in the figure above is
constructed. The electronic device shown at the top of the figure
is a power supply. One electrode compartment consists of a copper
strip placed in a 1.0 M CuSO4 solution, and the other
has a cadmium strip placed in a 1.0 M
Cd(NO3)2 solution. The overall cell reaction
is:
Cd2+(aq) + Cu(s) Cd(s) + Cu2+(aq)
