✦ Synopsis

Densities of (NH4)2SO4, K2SO4 and Al2(SO4)3 have been measured in dimetbyhulphoxide(DMS0) + water, co&in@ 0,5,10,15 aud 20 mass % of DMSO, at di&rent concetdrations and at 298.15,303.15,308.15 and 313.15 K From these densities, apparent molar volumes have been derived Tbe apparent molar volume data have been analyzed usiq Masson equation. 'Ihe limit@ appareut moler volume, V+O, end slope, Sv, are iuterpreted in terms of soluh-solvent and solute-solute interactions, respectively. The V@ values vary with temperature as a power series of temperature. Finally, the Structure makiqhreakii capacities of salts have been inferred Tom the Heplefs Cl%eliOlI
