LI.The effect of small water additions upon the conductivity of electrolytes in non-aqueous solvents

Summary 1. 1. The effect of small water additions upon the electrical conductivity of the following solutions has been measured :—Four salts in methyl alcohol.One salt in ethyl alcohol.Eight salts and two acids in acetone.2. 2. The viscosity of the various mixed solvents employed have been measured, and also the densities of the acetone-water mixtures.3. 3. The effects produced bv these water additions have been found to be proportional to the amount of water added, and on this observation a statistical view of ion solvation has been put forward.
