Tables 68 and 69 (figs. 54 and 55) show that lithium bromide, in mixtures of methyl and ethyl alcohols, gives no minimum in conductivity. In fact, the conductivity values for the solutions in the mixed solvent approach the mean value of the conductivities in the pure solvents. The conductivity curves at the high concentrations show a slight sagging at both temperatures, but beyond v = 50 the curves are nearly straight lines. This same fact has been observed by others working with mixtures of methyl and ethyl alcohols. The temperature coefficients obey, approximately, the law of averages. 1Amer. Chem.
