Part I. Constructing a Table of Standard Reduction Potentials
In this part of the experiment, you will be measuring the voltages of the several galvanic
cells diagrammed below. In other words, you will be using the "V" scales of the meters
(which you will find at the front of the laboratory.) Note that the meter display has both
an algebraic sign and a magnitude. Throughout this experiment you should clip the
"red" wire coming out of the meter to the "right hand" electrode of the cell in question. If
the meter shows a "plus" voltage, reduction takes place at that electrode. If the displayed
voltage is negative, oxidation is what really occurs at the "right hand" electrode of the
cell as diagrammed.
In most cases the cell electrolytes for Part I of the experiment will be 0.1 M stock
solutions of the nitrate salts of the various cations. For the cell containing a mixture that
is 0.1 M in both Fe2+ and Fe3+, you should mix together 1 mL volumes of the 0.2 M...
