Electrical conductivity of concentrated aqueous mixtures of HCl and KCl ina wide range of compositions and temperatures

The electrical conductivity of the HCl + KCl + H2O ternary system has been measured in a wide range of compositions (0 mol.dm(-3) < c(HCl) < 6 mol.dm( -3) and 0 mol.dm(-3) < c(KCl) < 1.2 mol.dm(-3)) and temperatures (15 degree s C < t < 45 degrees C) making use of an automated station for conductometr ic titration based on the "electrodeless conductivity" technique. The exper imental data obtained have been fitted to a polynomial in the HCl molar con centration, the KCl molar concentration, and the temperature. As a result, an empirical model enabling the interpolation of the conductivity of the ch emical system under study within the limits of the variables investigated h as been proposed.
