PROMPT: Write down as many correct, distinct, and relevant facts you can about: Copper can be measured in waste water by reaction with 1-(2-pyridylazo)-2-naphthal (PAN), which creates the substance copper(II)bis(PAN). The absorbance of a 25 mL sample was measured at 550 nm in a cell with path length of 1.00 cm. The value was 0.55 absorbance units. The molar absorptivity of the copper(II)bis(PAN) material is 2.05 x 104 M-1 cm-1. 6 statements are required for full credit. You may write...

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...
