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
manganese strip placed in a 1.0 M Mn(NO3)2
solution, and the other has a cobalt strip placed in a 0.5 M
Co2(SO4)3 solution. The overall
cell reaction is:
3 Mn2+(aq) + 2 Co(s) 3 Mn(s) + 2 Co3+(aq)
(a) Fill in the information necessary to complete the...
