| Abstract: | Relative viscosities for the solutions of some divalent transition metal sulphates, viz. manganese sulphate, cobalt sulphate, nickel sulphate, copper sulphate and zinc sulphate; and magnesium sulphate at different concentrations have been determined in water and in water + ethylene glycol (EG) [5,10,15 , 20 and 2S% by weight of EG] mixtures at 303.15 K, and in water and in 5% (w/w) EG + water at five different temperatures. The data have been analysed using the Jones-Dole equation and the obtained parameters have been interpreted in terms of ion-ion and ion-solvent interactions. The activation parameters of viscous flow have been obtained which depicts the mechanism of viscous now. The transition metal sulphates and magnesium sulphate act as structure makers/promoters in water and in EG + water mi xtures. |
