The radial pair distribution functions gHH(r) and gOH(r) (to a good approximation) of 1 and 10 m solutions of lithium chloride in water have been obtained from neutron diffraction. It turns out that the intermolecular water structure in a solution of 10 m is affected considerably by the presence of ions—the number of hydrogen bonds is about 70% lower than in pure water. The intermolecular water structure in 1 m lithium chloride as well as the intramolecular water structure in both 1 and 10 m lithium chloride is not distinguishable from that of pure water in any measurable extent.

    Cubic and hexagonal symmetries are observed in molecular dynamics simulations of lithium chloride unconstrained nanoclusters, using the Born-Mayer-Huggins (BMH) potential model. Phase changes between the two solid phases, and solid-liquid coexistences, are studied for LiCl clusters with a number...

    It is widely accepted that ice, no matter what phase, is unable to incorporate large amounts of salt into its structure. This conclusion is based on the observation that on freezing of salt water, ice expels the salt almost entirely as brine. Here, we show that this behaviour is not an intrinsic...

    Effect of adding an inorganic salt, lithium chloride, and water on viscosity of an ionic liquid, 1-n-butyl-3-methylimidazolium chloride (BmimCl), was investigated by shear stress measurements with a rheometer. Shear rate dependence of viscosity showed shear thinning behaviour, which implies that...

    The molecular structures of poly(vinyl alcohol) films cast from polymer aqueous solutions (1 mol/L) containing 0.1 mol/L of LiCl, NaF, NaCl, KCl, CsCl, KBr, and KI salts are studied via FTIR spectroscopy. The addition of any of these salts except LiCl leads to an increase in the degree of...

    A simple potential for the pair interaction of two water molecules is proposed. This model is intended for use in ionic solvation problems, and is a step beyond the ion dipole model proposed by Adelman, Deutch, and Blum to study molecular effects in solvation. It consists in adding to the hard...

    Neutron diffraction, in conjuction with substitution of deuterium (D) for hydrogen (H), has been used to determine the structure of interlayer water in sodium- and nickel-substituted vermiculites. We have measured the intensities of the (00l) Bragg reflections as a function of relative humidity...
