ABSTRACT
By now, no theoretical basis has been found for viscosity of concentrated electrolyte solutions [1], though numerous works on viscosity of solutions have been accumulated based on processing of proper experimental data and data from the world scientific literature systematized in [2]. In general terms, prevailing theories of liquid viscosity can be somewhat figuratively divided into those based on gas liquid and those based on crystalline liquid. The first of them considers liquid as having shortand long-range disorders. Theories of the second type assume that liquid has a regular structure, and momentum transfer occurs from molecules, which oscillate within lattice structure or which shift into closely spaced holes, or as a result of both of these phenomena. The selected crystal lattices have most diverse shapes-from cubic ones to those resembling parallel tunnels. These theories relate mainly to liquids, in which molecules do not dissociate into ions.
