Density and viscosity studies of sucrose and maltose in 0.5 M aqueous ammonium chloride solutions at 25, 30, 35 and 40°

P. G. Department of Physical Chemistry, M. S. G. College, Malegaon Camp-423 105, India J..A. T. Women's College, Malegaon-423 203, India Manuscript received 12 October 1998, revised 21 January 1999, accepted 19 March 1999 Viscosity data of sucrose and maltose solutions in water and in 0.5 M aqueous ammonium chloride at 25, 30, 35 and 40° are analysed with the help of modified Jones-Dole equation and the density data are analysed with the help of Redlich-Meyer equation. The apparent molar volume of transfer from water to aqueous ammonium chloride is also calculated. Results show that sucrose and maltose act as structure-makers in water and in aqueous ammonium chloride
