High-resolution low-frequency dielcometry is used to study changes in the structure aqueous solutions of electrolyte salts in the 10−2–10−6 М range of concentrations. Changes are recorded according to differences in tangent of dielectric loss, which reflects reactive processes in solution. All experiments are performed at room temperature. Experimental results in the 50–1000 kHz range of frequencies are presented as dependences of the dielectric loss tangent on the logarithm of frequency ω of the excitation of an oscillatory circuit. A glass test tube with the considered solution of electrolyte salt is placed in the inductance coil of the circuit. The observed dependences are of a pronounced spectral nature. The positions of the peaks in the spectra are reliably reproduced and characterize the cationic and anionic composition of a solution. Changes in the concentration in the observed spectra allow aqueous solutions of electrolyte salts to be attributed to classical solutions. [ABSTRACT FROM AUTHOR] |
