Investigation of electrolytic properties of liquid phase in ternary systems of lithium bromide-acetonitrile(pyridine)-nitromethane using the mathematical method of simplex design of an experiment

Electric conductivity and dynamic viscosity of liquid phases in ternary systems of liquid phases in ternary systems of lithium bromide-acetonitrile-nitromethane and lithium bromide-pyridine-nitromethane are studied everywhere over the region of salt solubility and mixed solvent compositions in the temperature range of 293.15-333.15 k; Mathematical models are obtained which describe the property-composition relationship. It is shown that the occurrence of extreme points on conductivity isotherms in the systems studied is attributable to lithium cation solvation with acetonitrile and pyridine. 21 refs., 4 figs., 5 tabs
