Unformatted text preview: he right-hand electrode of the cells as diagrammed above, which of these cells showed a positive algebraic sign for the measured voltage? 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...
