Abstract
The concentration dependences of molecular oxygen and hydrogen in aqueous solutions are studied with multiple dilutions and turbulent stirring accompanying the dilution procedure. Deionized water was saturated with molecular hydrogen and molecular oxygen by bubbling. The gas concentration was measured by polarographic methods. Upon reaching a specific number of dilutions, the concentration of impurities in the aqueous solution ceases to depend on the number of dilutions. The ability to observe this effect is determined by the sensitivity of the measurement method. The composition of the aqueous solutions can change under conditions of mechanical action. Mixing stimulates the capture of molecular oxygen from the atmosphere. The effect is more pronounced with turbulent stirring than with laminar.
