Rd. Oparin et al., Investigation of the structure of concentrated aqueous solution of LiCl atlow temperatures by the method of integral equations, RUSS CHEM B, 48(10), 1999, pp. 1858-1863
Peculiarities of the formation of the structure of aqueous LiCl solution (a
t a salt : water molar ratio of 1 : 5.3) in the temperature range 298-138 K
were studied by the method of integral equations. Analysis of the results
obtained suggests that transition of the system into the supercooled and gl
assy state is accompanied by an increase in the tetrahedral ordering of sol
vent molecules and a decrease in the number of interactions between the wat
er molecules in unbound solvent. Lowering the temperature leads to an incre
ase in the degree of structurization of water molecules surrounding the cat
ion. Preferable formation of hydrogen bonds with the anion under extreme co
nditions was established. The glassy state of the solution is characterized
by the absence of direct anion-cation correlations and increased (compared
to standard conditions) probability of the formation of ion-water chains.
