1.
Assume that the Cd
2+
+ 2e
-
Cd half reaction has an electrode potential of -0.403 volts as
indicated on the line scale below (1 division = 0.1 volt). Use your results to place the
reduction potentials of the six half-cells that can be calculated on the scale shown below.
Show all calculations for the experimental E
red
potentials plotted.
