Regularities of Conductivity of Aqueous Molecular Solutions

The work presents the results of measurements of specific conductivity in aqueous solutions of low–molecular alcohols: mono-, di-, tri-, and nonaethylene glycols, glycerol, ethanol, sorbitol, and acetone in the full concentration range. It is shown that not only hydroxyl groups should be considered as the donor–active charge carrier centers in the studied systems, but also oxygen atoms, which is illustrated by a linear dependence of the conductivity maximum on the number of hydration centers. A new method of normalization of specific conductivity is suggested that allows extracting the component corresponding to the charge carrier donor.
