Abstract

The physicochemical properties of NaCl aqueous solutions in a wide range of concentrations were studied. We determined that constant magnetic fields with an induction of up to 7 T had a significant effect on the physicochemical properties of these solutions. First, we detected a decrease in pH that was dependent on the magnetic field strength both in water and in NaCl solutions. This effect was not associated with the presence of sodium cations or chlorine anions in water. Secondly, with an increase in magnetic field induction the redox potential of aqueous solutions also increased. Magnetic fields did not cause any changes in the concentration of dissolved molecular oxygen in deionized water. In this case, in aqueous solutions of NaCl under the action of a magnetic field, a concentration-dependent tendency to a decrease in the concentration of dissolved molecular oxygen is observed. Third, it was shown that under the action of a magnetic field on a NaCl solution, the rate of hydrogen peroxide generation increased with increasing NaCl concentration. Fourth, the essential role of the primary state of aqueous solutions in relation to the gas composition and gas equilibrium under magnetic influence was established. The work also evaluated the contribution of flow-mixing during sample preparation on the physicochemical properties of the solutions.

Highlights

Water is the most common chemical compound of any living organism, including humans
The molecular oxygen concentration remained unchanged after the NaCl solution was diluted further
In the current study we investigated the changes in pH value, redox potential, and molecular oxygen concentration in NaCl solutions under the influence of magnetic fields of various inductances and in the absence of a magnetic field (Figure 1)

Summary

Introduction

Water is the most common chemical compound of any living organism, including humans. This can constitute 75% body weight in infants and 55% in the elderly [1,2,3]. The physicochemical properties of water undergo changes when chemicals are dissolved in it or it is exposed to physical factors [8,9,10,11,12]. This may have important implications in medicine, pharmaceuticals, agriculture, the food industry, and a number of related fields
