Do chaotropic and kosmotropic affects occur in polar non-aqueous media?
Chaotropic and kosmotropic effects of solutes can occur in any solvent in which interactions between solvent molecules lead to a more ordered structure, like a hydrogen bonding network in water. Such a network will also be present in alcohols like ethanol, although to a lesser degree, because the alcohol molecules have only one proton which can act as a hydrogen bond donor. The Hofmeister (or lyotropic) series for alcohols might still be similar to that for water (not identical), but it will be more different with increasing structural difference between the solvent molecule and water. In fact, the Hofmeister series for water is still not fully understood on a molecular basis, as it is described in this post, and this makes it difficult to predict Hofmeister series for other polar, non-aqueous solvents.
