The recently extended JonesDole equation still functions well for these systems up to a high concentration. It has been empirically found that when a seventh term of molarity was further added to the extended JonesDole equation, the viscosity for calcium chloride solutions and the mixed electrolyte solutions with larger ionic strengths could be excellently represented up to their saturated concentrations. In consideration of the large solubility of calcium chloride and furthermore of its large ionic strength and of its large viscosityconcentration coefficient, it could be supposed that the extented JonesDole equation in this work should fit many aqueous electrolyte solutions to their rather high concentrations or just to the saturated concentrations. In low concentrations, the calculated viscosity values obtained by simple additivity are close to the experimental values. Above a certain concentration, the calculated viscosities of NaCl + CaCl2 and KCl + CaCl2 mixtures are lower than the experimental values and the difference becomes larger with increasing concentration.
