Liquid Viscosity Of Binary Mixtures Of Isopropanol - Water Using The Ostwald Viscometer Method

Transcript

Liquid viscosities of pure isopropanol, as well as its binary mixtures with water were measured using the Ostwald viscometer – an instrument used to determine viscosities of fluid liquids. Mean liquid viscosities for the isopropanol and its binary mixtures were determined at room temperature (which was measured at T = 30C). As for pure water (sample A) and pure isopropyl alcohol (sample E), mean liquid viscosities for each sample were determined at various temperatures (T = 25,C, 50C and 70C) where n = 2.
