Abstract: Apparent molar volumes (Vφ) of myo-inositol in aqueous solutions of LiCl, NaCl, and KCl were obtained from densities, measured with a vibrating-tube densimeter, at 298.15 and 308.15 K. These data have been used to deduce limiting partial molar volumes Vθφ and limiting partial molar volumes of transfer ⊿trsVθφ from water to different salt solutions at different concentrations. The results indicated that influence of salt (LiCl, NaCl or KCl) on volumetric property of myo-inositol in aqueous solution was evident while temperature could only slightly change Vθφ and ⊿trsVθφ. The result was discussed in the light of interaction between the charged centers of myo-inositol and ions.

Key words: Limiting partial molar volume, myo-Inositol, Alkali metal salt
