Physicochemical and sweetness behavior of kosmotropic and chaotropic ions in aqueous solutions of polyhydroxy compound

Hydrated ions have essential applications in biochemical processes. The objective of the present work is to study the behaviour of kosmotropic and chaotropic ions in aqueous solutions of polyhydroxy compounds in terms of sweetness response, volumetric and acoustic parameters such as apparent molar volume (0v), apparent specific volume (ASV), compressibility (00k) etc. at different temperatures 20 degrees C - 45 degrees C and 101 kPa. The positive 0v values of arabitol showed more kosmotropic nature for Na+ ion developing more stabilize structure of arabitol with water through strong hydrogen bonding, while the presence of K+ and Cl- form weak hydrogen bonding with water termed as chaotropic ions. The ASV values showed that arabitol remained sweet in the presence of electrolytes. The negative results of 00k for arabitol in aqueous electrolytic solutions give valuable information about interactions occurring among solute, electrolytic ions, and water molecules. The structure-making/ breaking behaviour has been observed by Hepler's constant ( partial differential 20ov/ partial differential T2)p.
