Studying the action of different factors on th electrical conductivity of water

Abstract

Water is the most common substance of «our» world, but its properties Iiave not yet been fully studied. In the laboratory of nanostructuring of liquid media at the North Kazaklistan State University named after M. Kozybayev an experiment is being conducted to determine the electrical conductivity of different water samples. This paper presents the results of studies of the electrical conductivity of two types of water: flowing and boiled. The experiment was repeated with a decrease in the cooling time of the thermally treated water in order to exclude the effect of microorganisms on the composition of the water. During the experiment, it was found that the electrical conductivity of boiled water is higher than the electrical conductivity of miming water. The measurement results can serve as proof of the existence of a theory about the occurrence of non - polar monocluster Stractures in the volume of water under the influence of external overpressure.

Introduction

It is known that water in its pure form is a dielectric until impurities appear in it, which dissociate into conductive ions. The same theory speaks of the dependence of the concentration of free ions and electrical conductivity. However, there is an assumption that non - polar monoclusters exist in the volume of water (probably occur under pressure), the conductivity is low or even zero. If in reality there are such structures, then the conductivity of water should increase with different methods of its treatment. Previously, studies have been conducted showing an increase in the conductivity of water in after its treatment [1]. For more convincing evidence (there was a suspicion of microorganism interference), the experiments were repeated with a decrease in time, i.e. cooling water after heat treatment.

The experiment was carried out in the laboratory of nanostructuring of liquid media at the North Kazakhstan State University named after Manash Kozybayev. Two types of water were used for the experiments: 1) boiled water, 2) running water; electrodes, multimeters (ammeter, voltmeter), a source of alternating current with a frequency of 50 Hz, two glass vessels with a volume of 700 ml.

Initially, samples were taken in different vessels boiled and running water, then left for a while until the water reaches room temperature. In this case, the vessels were located at a distance of 3 meters from each other and were isolated from sunlight. The process of removing the volt - ampere characteristic took place as follows: electrodes connected to a current source and a multimeter were placed in a vessel with cooled boiled water, gradually changing the voltage (from 2 V to 20 V), the current was measured.

For the accuracy of the experiment, measurements were carried out several times, while waiting for the electrodes to dry and only then placing them again in the water and waiting for about 30 seconds for the electrodes to wet. The same was done with running water. The obtained values were entered into an Excel document and processed data directly in it. Measurements were taken in the afternoon. Examples of measurements are presented below in tables 1, 2, 3, 4.

According to the data obtained in the course of the experiment, graphs were drawn showing the dependence of the current strength on the voltage and you can clearly see the differences in the current conductivity of boiled and running water (Figure 1, 2).

Conclusion

This experiment showed that the electrical conductivity of water after boiling increases. This suggests the possibility of the existence of a theory about neutral mono - cluster structures in the volume of water, which impede the passage of current and collapse during boiling.
