Viscosity of Aqueous Electrolyte Solutions
Research Guide
What is Viscosity of Aqueous Electrolyte Solutions?
Viscosity of aqueous electrolyte solutions studies the concentration and temperature dependencies of dynamic viscosity in water-salt mixtures, incorporating ion-pairing and hydrodynamic effects.
Researchers measure viscosities across electrolyte concentrations and temperatures, correlating data with Jones-Dole parameters (Jones and Dole, 1929; 1342 citations). Extended models account for non-ideal behaviors in strong electrolytes like barium chloride. Over 10 key papers span from 1929 to 2014, with 5000+ total citations.
Why It Matters
Accurate viscosity predictions enable design of fluid transport systems, heat exchangers, and electrochemical cells in chemical engineering. Jones and Dole (1929) established foundational correlations used in industrial electrolyte processing. Kawahara and Tanford (1966) provided density-viscosity equations for urea solutions applied in biochemical separations. Cheng (2008) extended empirical formulas to glycerol-water mixtures for process simulations, while Salis and Ninham (2014) explained Hofmeister ion effects impacting protein stability in biotech.
Key Research Challenges
Non-ideal Ion Interactions
Ion-pairing and hydration shells deviate from ideal hydrodynamic models at high concentrations. Jones and Dole (1929) introduced parameters but struggle with multivalent ions like barium chloride. Modern extensions needed for precise predictions.
Temperature-Concentration Coupling
Viscosity varies nonlinearly with both temperature and concentration, complicating empirical fits. Kawahara and Tanford (1966) measured urea solutions at 25°C, but broad ranges remain underexplored. Angell and Sare (1970) highlighted glass-forming behaviors at low temperatures.
Hofmeister Series Specificity
Specific ion effects follow Hofmeister series, affecting viscosity beyond charge density. Salis and Ninham (2014) revisited mechanisms in electrolyte solutions. Integrating these into predictive models challenges universal correlations.
