Analyzing electrolytic conductivity data by the Fuoss-Justice equation with a programmable calculator

Abstract The dissociation constant K c and the equivalent conductivity at infinite dilution Λ of 1-1 electrolytes are computed according to the Fuoss-Justice method as well as modifications of this program to analyze symmetric z:z electrolytes. The algorithm is presented for a Texas Instruments TI 59. The analyzing of electrolytic conductivity with a programmable calculator by the simple Fouss-Krauss method has been described earlier (Rechberger & Linert, 1980). In this work a much better and more complete model should be used, called the Fouss-Justice model (Wachter & Barthel, 1979; Barthel et al., 1973; Barthel, 1976; Fouss & Hsia, 1967).
