Density and Viscosity Studies of Aqueous Solutions of Cesium Trifluoroacetate at Different Temperatures

Abstract

Densities and viscosities of aqueous solutions of cesium trifluoroacetate have been measured at T ) (298.15, 303.15, 308.15, and 313.15) K and at atmospheric pressure. Apparent molar volume (φ v ), partial molar volume (φ o v ), and the ion-ion interaction parameter (S v ) have been calculated from experimental values of densities. The calculated values for φ o v are (105.522

Viscosities of Ammonium Sulfate, Potassium Sulfate, and Aluminum Sulfate in Water and Water + N,N-Dimethylformamide Mixtures at Different Temperatures

“…Masses were recorded on a Dhona balance with a precision of ± 1·10 −7 kg. The densities (ρ) of aqueous solutions were measured with the help of a 15·10 −6 m 3 double arm pycnometer. , The uncertainty in the density measurements was ± 1·10 −7 kg·m −3 .…”

“…The dynamic viscosity of solutions was calculated using the equation where ρ, ρ o , t , t o , and η, η o are density, flow time, and viscosity of aqueous solutions and water, respectively. Viscosity measurements were made in a transparent glass-walled water bath − having a thermal stability of 0.01 K. Viscosity measurements were made as a function of concentration (0.0080 and 1.0000) mol·kg −1 of salts and temperature (298.15 and 308.15) K at atmospheric pressure. The uncertainty in the viscosity measurements was 3·10 −6 m −1 ·kg·s −1 .…”
