Viscosities of R4NI (R = CH3 to C4H9), NaI and NaBh4 solutions 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.
