Abstract: The relative viscosities of solutions ofLiO4, LiClO4, NaNO3. NaSCN. Kl, KSCN, AgNO3, Bu4NBr, Bu4NI, NaBPh4 and Bu4NBPh4 have been measured in the concentration range (6.89744.0)x 10-4mol dm-3 in N-methyl-2-pyrrolidinone at 25°C. The viscosity data have been analysed by the Jones-Dole equation and viscosity B-coefficients have been found to be positive. Ionic viscosity B- coefficients are obtained by splitting B-coefficients of Bu4NBPh4  into contributions due to individual ions in terms of their radii. The ionic viscosity B-coefficients follow the order: Li+> Na+ > K+ and BPh4- > SCN- > Br-> I-> CIO4- > NO3- > Cl-.
