Abstract
An apparatus for measuring the dielectric constant of conducting solutions by voltage resonance is described. The theory of the circuit and the sources of error are discussed. The design of the apparatus is such as to eliminate errors other than those due to inductance of cell leads, for which a correction is made.Measurements have been made on solutions of sodium chloride, hydrogen chloride, potassium sulphate, magnesium sulphate, copper sulphate and potassium ferrocyanide, at 23.0 °C. and 2 × 106 cycles frequency. An increase in dielectric constant with concentration greater than that predicted by Debye and Falkenhagen has been found in all cases. The results are compared with those of other workers. Graphs are given of the results obtained.
