“…Therefore, one is faced with the problem of determination of hydration number uniquely so that information about solute-solute and solute-solvent interaction can be studied conveniently and examined with the help of theories like Flory-Huggins and McMillan-Mayer in solution phase [7]. Recently, we developed a method for determination of hydration number for tetra-n-butylammonium bromide (as a compressible solute) in aqueous solution by making use of compressibility data [8,9] and modifications in Shiio's method [10] (reported earlier) to estimate the bound water.…”

Physicochemical properties of diethylammonium (DEA)-based protic ionic liquids and their aqueous solutions were obtained using experimental measurements of density (ρ) at different temperatures from T = (293.15 to 313.15) K and the speed of sound (w) at 298.15 K. Four DEA-based protic ionic liquids (PILs) with carboxylates as anions were synthesized. The standard entropy (S 0 ) and lattice potential energy (U POT ) for pure PILs were estimated from molecular volumes at 298.15 K obtained using experimental density data. Apparent molar volumes (ϕ V ), isobaric expansivity (α), isentropic compressibility (β S ), and isothermal compressibility (β T ) have been obtained for aqueous solutions of PILs using experimental density and speed-of-sound data. These data have been further used to understand the electrostriction and concentration dependence of internal pressure. The Passynski method has been used to estimate concentration-dependent hydration numbers of PILs. The results obtained have been discussed in terms of concentration-and temperature-dependent hydrophobic hydration, hydrophobic ion association, water structural changes, and so on. It has been observed that hydrophobic hydration persists in the entire studied concentration and temperature ranges. A critical examination of the data and results obtained reveals that the studied bio-ionic liquids can act as potential candidates in the pharmaceutical industry and in protein chemistry.
