Verification of electrolytes
solvation from diluted to concentrated ones in water solution
Abstract
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: h – hydration numbers, bhVh – molar adiabatic
compressibility of hydration formations, V1h – volume and b1h – compressibility of
water in hydration shells of ions and others. It is shown that quantities h 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.
