Dynamic Viscosities of KI or NH4I in methanol and NH4I in ethanol at several temperatures and 0.1 MPa
Viscosities and densities have been determined for some binary strong electrolyte solutions-KI + methanol, NH4I + methanol and NH4I + ethanol-at (298.15, 303.15, 308.15, and 313.15) K and 0.1 MPa. The viscosity data have been analyzed using the three-parameter Jones-Dole equation (Kaminsky, M. Ion-solvent interaction and the viscosity of strong electrolyte solutions. Discuss. Faraday Soc. 1957, 24, 171-179), and the A B, and D parameters have been calculated. A Debye-Huckel model for calculating the viscosity proposed by Esteves et al. (Esteves, M.; Cardoso, M.; Barcia, O. A Debye-Huckel model for calculating the viscosity of binary strong electrolyte solutions. Ind. Eng. Chem. Res. 2001, 40, 5021-5028.

Res. 2002, 41, 5109-5113) has been used to correlate the experimental data.
