Abstract
Pressure and concentration dependences of viscosity for aqueous KCl and Csl solutions were examined at 298.2K and compared with those for aqueous NaCl and CsCl solutions. The viscosity minimum, observed for pure water with increasing pressure, became shallow or disappeared by adding alkali halides. The Jones-Dole B coefficients for Na+, K+, Cs+, Cl-, and I- increased with increasing pressure and then decreased after having a maximum. These results are discussed in terms of water structure and dielectric friction effect.
