Polarographic investigations were conducted on melts in the form of solutions of CuCl, CuCl/sub 2/, AgCl, ZnCl/sub 2/, CdCl/sub 2/, TlCl, PbCl/sub 2/ , CoCl/sub 2/, and NiCl/sub 2/ in in a NaCl-KCl mixture. A direct proportionality between the intensity of the diffusion current and the molar fraction of the dissolved chloride is shown for the investigated melts. The polarographic waves obtained on solid Pt electrodes are satisfactorily described by the Heyrovsky-Ilkovic equation. These waves do not obey the KolthgroffLingane equation of concentration polarization; in particular, the dependence of the half- wave potential on the logarithm of the molar fraction is not expressed by a straight line. The values of the half-wave potentials remain approximately constant. The values of the prelogarithmic coefficients in the Heyrovsky-rlcovic equation do not always correspond to the valency of the simple ions of the respective salts. The investigation of the dependence of the difiusion currents on the temperature permitted calculating the corresponding energy activation, these values showing that the increase of diffusion currents does not depend solely on the decrease in viscosity.
