Dielectric Constant Studies. I. An Improved Voltage Tuning Resonance Method and Its Application to Aqueous Potassium Chloride Solutions

Abstract

An experimental study of the behavior of various types of apparatus used in the measurement of dielectric constants of aqueous solutions of electrolytes. Although simple theory indicates that the voltage tuning method of detection should give results which are uninfluenced by the conductivity of the solutions and should, hence, be particularly adapted to measurements on electrolytic solutions, it appears, however, that other disturbing factors are present. This is shown by the divergent results obtained when different types of detection are employed and leads to the conclusion that the change in dielectric constant of such solutions as observed by this method depends more or less upon the characteristics of the particular generating and receiving circuits used.
