Experimental study of the electrical conductivity of water, dilute aqueous solutions of alkali metal chlorides and alcohols under the electromagnetic field influence

Abstract

The article is devoted to the study of the influence of a high-frequency electromagnetic field on the electrical conductivity of water, aqueous solutions of alkali metal chlorides and dilute aqueous solutions of normal alcohols. A significant increase in the electrical conductivity of water and aqueous solutions under the influence of the electromagnetic field with a frequency varying in the range of 100–200 MHz is found. The effectiveness of the electromagnetic field impact depends on the frequency of the field and the time of its action. The electrical conductivity of water and aqueous solutions of alcohols increases to the greatest extent, more than twice. The effect of field influence on the electrolytes solutions is sufficiently lower and appears only for the solutions with concentrations of less than 0.01 mol/L. The maximum increase in electrical conductivity of is observed in 10–4–10–3 M sodium chloride solutions and is 27–33 %. After the termination of the field action, the electrical conductivity of the electrolytes solutions slowly relaxes to the initial values, and the electrical conductivity of water and aqueous solutions of alcohols continues to increase for 7–10 days until a stationary value is established. The observed phenomena can be caused by a change in the structural organization of water as a result of electromagnetic interference.
