Our preceding papers dealt with the experiments on the measurements of the concentration of the electrolytic solutions, such as NaCl, Na
2SO
4, (NH
4)
2SO
4, HCl and KOH by the use of the "High-Frequency Concentration Meter, " from the results of which experiments was concluded that the response-curves were influenced by the frequency, the shape and size of the cell condenser, the conductivity of the solution and so on.
In this paper are reported the relations between the the response-curves and such variables as described above.
(1) The frequenceies of the working oscillator of several types (containing the cell and solution) were calculated by the analytical method as the functions of the conductance, the capacitance of the cell, solution and coils and condensers of the apparatus; the results obtained being shown in Table 1.
(2) The relations between the output current or frepuency of the response-curve and the ω, c1, c2 and L were calculated and the results are shown in Table 2 and Figs. 3 and 4.
(3) The relations between the response-curve and the cell constant, frequency, temperature, etc. were calculated for the electrolytic solution, and the results obtained are shown in Figs. 5, 6 and 7.
