. Carnegie Institution of Washington publication. Fig. 39. Conductivity of cobalt chloride in mixtures of ethyl alcohol and water at 0°. 10. 25 50 75 Per cent, of ethyl alcohol 100 The curves representing dissociation in ethyl alcohol-water mixtures are sometimes upward curves, taking a direction opposite to that of the curves representing conduc- tivity, which are downward curves. This fact is especially apparent when fig. 35, giving the curves for the conductivity of potassium iodide in mixtures of ethyl alcohol and water at 0°, is compared with fig. 41, which gives the curves for the dissociation of these same solutions. This plainly indicates that the greatly diminished conduc- tivity in mixed solvents is due not to diminished dissociation, but to the other factor conditioning conductivity, viz, diminished velocity of the ions through the solution. Though it had been previously pointed out that this diminished conductivity is due almost entirely to increased viscosity of the mixed solvent, it was not definitely known what the magnitude of the dissociation in these mixed solvents is, nor was it suspected that this dissociation might be greater in the mixed than in the pure sol- vents, as is shown to be the case by the curves for dissociation, some of these curves having maxima, while those of conductivity have decided minima. These facts are quite marked where ethyl alcohol-water mixtures are used as solvent. In such cases.
