It was shown previously that the shape of the crystals formed during the evaporation of salt solutions depends on the sign of the electric potential of such solutions. It has been particularly found that the evaporation of salt solutions with positive electric potential is accompanied by the formation of cubic crystals and the evaporation of salt solutions with negative electric potential is accompanied by the formation of needle-like crystals. The obtained results stimulated further studies of the properties of water and aqueous solutions, which depend on the electric potential. During these studies it was found that the surface tension of the water clearly depends on its electrical potential: an increase in the positive electric potential of water is accompanied by an increase in its surface tension and increase the negative electrical potential of the water is accompanied by a decrease of its surface tension. It was also discovered that the electrical potential of the water determines its ability to hydrate the polymers of biological origin. It is shown that water with a positive potential is better hydrates biological polymers than water with negative potential.
