摘要
Molar conductance and density of the [xNaSCN + (1 - x)KSCN] + RH2O system were measured as functions of x, R, and temperature (283-323 K). Deviation of molar conductance from additivity occurs at all the temperatures in the region R less-than-or-equal-to 10. The amount of this deviation is found to be independent of temperature. The isothermal concentration dependence of molar conductance was described by the expression LAMBDA = LAMBDA-FLK exp(Bc + Cc2), where LAMBDA-FLK is the Falkenhagen-Leist-Kelbg equation for LAMBDA. B and C are empirical constants, and c is the molar concentration. The temperature dependence of LAMBDA has been described by the Vogel-Tammann-Fulcher equation.
