. Carnegie Institution of Washington publication. 94 CONDUCTIVITY AND VISCOSITY IN MIXED SOLVENTS. Tables 55 and 56 (figs. 28 and 29), for potassium iodide in mixtures of acetone and methyl alcohol, show that the conductivity is almost exactly what we should expect from the law of averages. There is, however, a slight tendency towards a maximum as we raise the temperature. In this respect the results are similar to those obtained with lithium nitrate. The values for the conductivity of potassium iodide in pure water, and ethyl and methyl alcohols, were taken from the work of Jones and Lindsay.

Tables 56 and 57 (figs. 30 and 31) show the same characteristics for potassium iodide, in mixtures of acetone and ethyl alcohol, as those observed for the same salt in mixtures of acetone and methyl alcohol, but there is less of a tendency towards a maximum. In fact, there is a slight sagging in the curves. It is observed that this statement is almost identical with the one in regard to lithium nitrate in mixtures of acetone and ethyl alcohol. Tables 55 and 56 (figs. 32 and 33), for potassium iodide in mixtures of acetone and water, display a minimum in molecular conductivity. There is no tendency towards a maximum. It should, however, be noticed that the divergence of the curves between the 75 per cent mixture and pure acetone is small. The salt is, therefore, quite largely dissociated at all dilutions in all of the mixtures. It was thought advisable, at this stage, to use solutions of sodium iodide in the various mixtures. Solutions of sodium iodide in acetone had been investigated by Carrara,1 by Dutoit and Friderich,2 and by It was 1 Gazz. Chim. Ital., [1] 27, 207 (1897). 2 Bull. Soc.
