Ionic Viscosity B-Coefficients of (CH₃)₄N⁺, (C₂H₅)₄N⁺, (C₃H₇)₄N⁺, (C₄H₉)₄N⁺, Na⁺ , I^- and Bph₄^- in Aqueous Methanol at 298.15 K

Abstract

Viscosities of R₄NI (R = CH₃ to C₄H₉), NaI and NaBh₄solutions in 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 mass % of methanol + water at 298.15 K were measured. The viscosity data have been analyzed with the help of Jones-Dole equation. The corresponding viscosity `B` coefficient is calculated. Ionic B coefficients of cations and anions have been determined using Bu₄NBPh₄ as reference electrolyte.
