Lyotropic Order and the Effects of Sodium Salts on the Miscibility of Cyclohexane and Methyl Alcohol.

Abstract

In 1888, while investigating the salting out of natural egg albumin from aqueous solutions, Hofmeister (12) found that the various ions were effective to different extents and arranged the two groups in their resulting order. Later Pauli (18) modified and extended the series, giving for the salting out of albumin:

2D-Ising-like critical behavior in mixtures of water and 3-methylpyridine including antagonistic salt or ionic surfactant

“…Fig. 2 confirms that the SANS profile from the binary mixture of D 2 O and 3MP is explained by eqn (1). The temperature dependence of the forward scattering and correlation length near the critical temperature T ¼ T c should be…”

“…The effect of adding a salt, such as NaCl and NaBr to the phase separation has been investigated experimentally owing to the drastic expansion of the two-phase region. [1][2][3][4][5] These effects can be explained in terms of the cluster formation in a one-phase region attributable to the solvation effect of ions. 6,7 A mixture of heavy water and 3-methylpyridine (3MP) is a typical system used to investigate the effect of salt on the phase separation.…”

Effects of Internal and External Ionic Environment on Excitability of Squid Giant Axon

“…In salting-out experiments, the behavior of cations is rather complex. Many examples may be found (Gortner et al, 1928;Frey and Landis, 1932;Eckfeldt and Lucasse, 1943;Hber 1928;Haldi et al, 1927), where the cation order changes with concentration, pH, and temperature, as well as with the nature of the colloid concerned.…”
