Structure of the Water Solution

Affected by the forces of inter-atomic and inter-molecular interactions, almost all atoms in ground water turn out to be to some extent associated. Numerous weak intermolecular bonds, not taken into account at chemical analysis, whose effect grows with increase in pressure, salinity and with the decrease in temperature and rate of flow, have special significance. All these bonds obstruct translation mobility of individual atoms and thereby facilitate the formation of some structure of the solution, which determines its physical and chemical properties in reservoir conditions. Aqueous solution structure is some relatively stable in space and time optimum orderliness of inter-atomic and inter-molecular bonds in the specifically set conditions. This structme depends on temperature, pressure and composition of water in the reservoir conditions. 

As mentioned above, in the absence of alien components H O molecules are positioned in a certain order, forming their own structures, similar to a tetrahedron. Moreover, the strength of these structures and orderliness of the O and H atoms decrease with the growth in temperature. 

Alien components forming solution disrupt the orderliness of pure water. The nature of such disruptions depends first of all on the properties of these components. 

Much greater effect on the structure of ground water render polar hydrophilic components, among which ions play the main role. For them, water serves as a strong protolytic solvent, which  

is capable of entering orientation interaction with them, creating hydrates
