Viscosity and density of chrom alum in aqueous poly (ethylene glycol)‎ solution at different temperature

الملخص EN

Density data of alum chrom in water and in aqueous solution of poly (ethylene glycol) (1500) at different temperatures (288.15, 293.15, 298.15) k have been used to estimate the apparent molar volume (Vθ), limiting apparent molar volume (Vθ˚) experimental slope (Sv) and the second derivative of limiting partial molar volume [δ2 θ v° / δ T2] p .The viscosity data have been analyzed by means of Jones–Dole equation to obtain coefficient A, and Jones–Dole coefficient B, Free activation energy of activation per mole of solvent, Δμ10* solute, Δμ20* the activation enthalpy ΔH*,and entropy, ΔS*of activation of viscous flow.

These results have been discussed in terms of solute–solvent interaction and making / breaking ability of solute in the given solution.
