Aqueous solutions of a “green” ionic liquid and of lithium chloride compared and contrasted

Abstract

Aqueous solutions of (a) a “green” ionic liquid and (b) lithium chloride are considered here. Proposals are made in respect to momentum transfer as characterized by shear viscosity, η. Arrhenius-type behavior as a function of temperature is contrasted with possible power-law form. More generally,  η is written as a product of mass density, the velocity of sound squared, and a characteristic time. Experiments are proposed for testing present ideas also involving the Debye–Hückel screening length.

Keywords:
