| Abstract | By the method of Flicker Noise Spectroscopy (FNS) we studied the process of sodium chloride dissolving in water (3.5 wt %) at 294 K on the level of long-range order formation in liquid. It is established that the process of dissolving the salt includes the following steps: formation of instable colloid particles, instable solvate clusters of the salt ion pairs (iSCIP), instable dissolved polymers of globular type, and 12 h later beginning of a new process of formation stable solvate clusters of the salt ion pairs (sSCIP) and stable polymer globules on their basis. Stroke diagrams of the cluster nano-structure and a model of aging the salt solution are presented. Influence of atmospheric pressure on the SCIP average weight is demonstrated. It is concluded that on the SCIP surface there is a porous layer of solvate water with membrane properties. The cluster structure of the 3.5 wt % solution prepared by dissolving the salt is shown to differ from that of the solution obtained by dilution. The solutions long-range order is formed by the nano dispersion of the water solvated salt crystal nuclei. The mechanism of the solution aging is discussed. |
