The densities and viscosities of ammonium nitrate, lithium nitrate, sodium nitrate, potassium nitrate, magnesium nitrate, and calcium nitrate in water have been measured at the temperatures (303, 308, 313, 318, and 323) K. The. apparent molar volumes (V-phi) and viscosity B coefficients of these salts are obtained from these data supplemented with their densities and viscosities, respectively. The limiting apparent molar volumes (V-phi(o)) and experimental slopes (S-V*) derived from the Masson equation have been interpreted in terms of ion-solvent and ion-ion interactions, respectively. The viscosity data have been analyzed using the Jones-Dole equation, and the derived parameters B and A have also been interpreted in terms of ion-solvent and ion-ion interactions, respectively. The structure making/breaking capacities of these salts investigated have been discussed. The compressibility data also indicate the electrostriction of the solvent molecules around the metal ions.
