The electrolytic cell consisted of two crucibles filled with a eutectic mixture of LiCl and KCl and connected by a salt bridge filled with the same salt. Electrical contact was made through a very thin glass diaphragm in the wall of the salt bridge. The anode was a pool of molten lead in contact with a carbon rod protected from the fused salt by a quartz tube. A tungsten wire 0.6 mm in diameter protected by a refractory glass served as the cathode. Polarization curves were run at 450 deg C in the neutral electrolyte of LiCl and KCl for 0.04 to 0.24 wt% of PbCl/sub 2/, CdCl/sub 2/,MgCl/sub 2 and NaCl. Plots of lg i/sub k/ (i/sub s/-i/sub k)! versus the cathode polarization E(V) gave a series of straight lines for Pb, Cd, Zn, Mg and Na. The term i/sub k/ is the cathode current, and is is the saturation current. A plot of the saturation current i/ sub s/ versus the concentration of metal in the melt gave a straight line. The half-wave potentials with respect to the chlorine electrode were found to be - l.68 volts for Pb, - 1.81 volts for Cd, - 2.00 volts for Zn, - 3.10 volts for Mg, and - 3.22 volts for Na. (TTT)
