Apparent molar volumes and apparent molar compressibilities for d-mannitol in (1, 5 and 10) % aqueous sodium or magnesium chloride have been determined from solution density measurements at T=(293.15, 298.15, 303.15, 308.15, 310.15, and 313.15)K and sound velocity measurements at T=(293.15 and 310.15)K as a function of the concentration of sugar alcohol. The limiting apparent molar volumes and limiting apparent molar compressibilities have been obtained from the Masson equation. The corresponding transfer parameters and expansion coefficients were also estimated. These parameters have been discussed in terms of d-mannitol-cosolute (NaCl or MgCl(2)) interactions in aqueous solutions and thus used to understand the mixing effects due to these interactions.
