We test a proposed relation between mutual diffusion coefficient and viscosity in suspensions which is essentially identical to a dynamic mode-coupling theory of diffusion in binary fluid mixtures near a critical mixing point. In contrast to conventional treatments of suspension hydrodynamics, this
The viscosity B-coefficient, B,, of the total salt was found to be linearly related with the molal volume, v&, of the hydrated salt according to the equation, B, = aV$, -b. The coefficients a and b were calculated to be 2.8, and 0.19, at 25ยฐC and 2.6, and 0.20, at 5"C, respectively. The V& values at
