Part A and B
Please show all of the steps
Analysis of Electroplating When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode. The amount of metal plated depends on the number of electrons passed. The total charge of a mole of electrons is...

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)
(a) Fill in the information necessary to complete the half
reactions...
