Equilibria salts, relaxation behavior

It has been shown in Fig. 4 that the relaxation time x of each electrolyte solution was always longer than that of water in both monovalent and divalent salt aqueous solutions. With increasing salt concentration, not only the relaxation time but also the viscosity 77 of the solutions increases. In Fig. 4 the ratio of viscosity rj/rjwater is shown as a function of concentration. From this figure we can see that the concentration dependence of the ratio x/Xwater has almost the same behavior with that of the ratio n/Hwater- The viscosity is derived from the dynamical property of liquid. From a microscopic point of view, the molecules should be rearranged each other when flow occurs. The relaxation of structure is the process by which molecules of a system "flow" from a non equilibrium configuration to a new...
