Transport studies of alkaline earth metal chlorides in binary aqueous mixtures of sucrose at different temperatures

Abstract

Viscosities of some alkaline earth metal chlorides viz; calcium chloride and magnesium chloride have been determined in binary aqueous mixtures of sucrose (3, 6, 9 and 12% by weight of sucrose) with the help of density measurements at one temperature 303.15K. Effect of temperature has also been studied by taking equidistant temperatures (298.15, 303.15, 308.15, 313.15 and 318.15K) for these electrolytes in 3% (w/w) sucrose + water. Viscosity data has been analysed by using Jones – Dole equation and B-coefficient values are determined. The obtained parameters have also been interpreted in terms of ion –ion and ion – solvent interactions. In the present study, magnesium chloride and calcium chloride act as structure breakers in sucrose + water system.
