文摘

The densities (蟻) and viscosities (畏) for sulphanilamide, sulphanilic acid, and sulphosalicylic acid dihydrate in aqueous solutions of magnesium chloride hexahydrate (0.05, 0.1, 0.25, and 0.5) mol路kg^鈥? at temperatures from (288.15 to 318.15) K have been measured by using vibrating tube digital densimeter and Micro鈥揢bbelohde type capillary viscometer, respectively. These data have been used to obtain partial molar volumes (V₂⁰) at infinite dilution and viscosity B coefficients. The present partial molar volumes and B-coefficient data in conjunction with that reported in water have further been used to calculate the corresponding transfer parameters (螖_trV₂⁰ and 螖_trB). The results have been compared with the data already reported for these drugs in aqueous sodium chloride solutions.
