Y. Yoshimura et al., EFFECTS OF PRESSURE, TEMPERATURE, AND CONCENTRATION ON THE VISCOSITY OF AQUEOUS AMMONIUM BROMIDE SOLUTION, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 50(2-3), 1995, pp. 316-322
The viscosity of aqueous ammonium bromide solutions is measured at 0.1
-1.0 mol kg(-1), 278.2-323.2 K, and 0.1-375 MPa, using a high-pressure
rolling-ball viscometer. The activation energy (E(v)) for viscous flo
w and Jones-Dole's B coefficient are estimated. E(v) against pressure
yields a concave curve with a minimum and B yields a convex one with a
maximum. These phenomena are attributed to pressure, temperature, and
concentration effects on the water-structure.
