Abstract
The frequency dependence of the electrolytic conductivity
was studied for solutions of varying concentrations of NaCl,
MgS04, KC1, and KBr. An experimental test fixture was
designed and an equivalent electrical model of the test
system developed. A theoretical model of the conductivity
that accounts for charge carrier inert: a is proposed.
Measured values of the impedance at various frequencies
were used to generate test system model parameters, and
subsequently identify sample response. Interpretation of
the sample response using the conductivity model allowed
determination of the conductivity, which is presented in
the form of the D.C. value or real part, Ko and the nondielectric
time constant, Tc. The conductivity of the
solutions decreased with increasing frequency and the
initial measurements of Tc were of the order of nanoseconds.
Variations in K with salinity were in agreement with the
empirical formula of Walden.
