Evaluation of the Features of the Structure of Water and Aqueous Solutions Near a Solid Surface

Abstract

The paper evaluates changes in the structure of water and aqueous solutions of sodium chloride in the wall layer on the basis of dielectrometry and correlation analysis. It is shown that when the distance to the solid surface decreases, there is a multi-fold nonlinear decrease in the electrical capacitance and a nonlinear change in the Sr parameter, which characterizes the magnitude of the change in the electrical capacitance of the conduction fluid when the distance to the solid surface changes. The parameters used in the work (electric capacity of liquids and Sr ) can be used to evaluate the changes in the structural organization of aqueous solutions in the wall (boundary) layer and to interpret the processes occurring in the liquid layer at the interface of the solid – aqueous solution phases.

Using Methods to Assess the Structure of Water and Water-Containing Systems to Improve the Properties of Living and Non-Living Systems

“…Secondly, when using electrophysical methods in measuring cells through water and water-containing systems, the minimum possible current values from 10 nA/cm 2 to 780 nA/cm 2 are used. At the same time, the research results in various papers did not contradict each other [17,21,22,26,29,[40][41][42][43][44][45][46][47][48][49][50].…”

“…The authors of [46] investigated how the temperature in a measurement cell changed when they cooled down distilled water and salt water from 10 • C to 1 • C. They found that the temperature change curves exhibited some local fluctuations that were more noticeable than in [44] (see Figure 2).…”

“…Conversely, the local maxima are caused by a structural shift in the water with heat release (and, therefore, with the formation of larger clusters). In a more concentrated solution of sodium chloride (1.5 × 10 −1 M), larger clusters may form with a more noticeable drop in temperature (from 3 • C to 2 • C) [46].…”
