Relative viscosities of divalent transition metal sulphates solutions, viz. manganese, cobalt, nickel, copper, zinc and magnesium sulphate has been determined in water–diethylene glycol mixtures. Effect of temperature on the viscosities at 298.15–318.15 K has been studied and B coefficients of Jones–Dole equation are determined for these solutions. The obtained parameters have been interpreted in terms of ion–ion and ion–solvent interactions. Magnesium sulphate is taken as the reference electrolyte to see the change in the behavior of divalent ions when we shift from divalent transition metal ions to some other divalent ions in these solutions. Here these transition metal and magnesium sulphates behave in the same manner i.e structure makers in both water and in DEG + water mixtures.
