Indira Gandhi Home Science Girls P G College Shahdol, MP > Short Communication 2021 3 22 2022 02 18 Precise Viscosities and Densities for Acetonitrile-water mixtures containing 10, 20, 30, 40, 50, 60, 70% by weight have been determined at 25ºC where possible the data are compared with previously reported values. The use of mixed solvents enables the variation in properties such as dielectric constant and Viscosity and therefore, the ion-ion and ion-solvent interactions can be better studied.
