VERIFICATION OF ELECTROLYTES SOLVATION FROM DILUTED TO CONCENTRATED ONES IN WATER SOLUTION
On the basis of the literary data on density, a thermal capacity and speed of distribution of ultrasound research solvation parameters of water solutions of strong electrolytes has been made. With use of correct thermodynamic parities at change of temperature from 278.15 to 323.15 K such quantitative parameters of solvation as are defined:<i> h</i> - hydration numbers,<i> b</i><sub><i>h</i></sub><i>V</i><sub><i>h</i></sub><i></i> - molar adiabatic compressibility of hydration formations, V<sub>1h</sub> - volume and b<sub>1h</sub> - compressibility of water in hydration shells of ions and others. It is shown that quantities<i> h</i> and don't depend on temperature in the investigated interval of conditions, and electrostriction compression about ions makes stronger impact on its structure, than simple change of pressure.
