Unformatted text preview: he right-hand electrode of the cells
as diagrammed above, which of these cells showed a positive algebraic sign for the
Part II Analysis. When a measured cell voltage is negative, the electrode to which the red
lead is attached is actually the anode rather than the cathode. The anode is the electrode
at which oxidation takes place, so it is surrendering electrons to the external circuit. For
the two cells involving the iron and copper species, the Cu(II)/Cu(s) couple is the anode.
Which of the following half-cell reactions is taking place at the Cu electrode in the anode
compartment of these two cells? Three choices will be given
Part II Analysis. You will now calculate the theoretical cell voltage differences for the
three concentration cells involving the copper and iron, cells #3, #5, and #6, and compare
your experimental results with these predictions.
Part II Analysis. For the overall cell reaction in cells #3, #5, & #6,
Cu(s) + 2Fe3+(aq) 2Fe2+(aq) + Cu2+(aq), which o...
