I. The Observed Cell Potentials Cathode Anode Potential (V) Cu Zn 0.928 Cu Sn 0.608 Cu Fe 0.565 Cu Pb 0.509 Sn Zn 306.5 Fe Zn 364.3 Pb Zn 0.4 Fe Sn 63.2 Pb Sn 116.2 Pb Fe 55.6 II. The Multimeter The reading on the multimeter must be positive because E 0 must be positive. If the reading is negative then the cathode and anode must be switched. E cell (positive) equals the E cathode minus the E anode.
