Viscosity of Electrolyte Solutions 

 

Download Application Note

The viscosity of various electrolyte or salt solutions was measured to illustrate the ability of the fully automated VROC® initium to distinguish low viscosity fluids. The Jones-Dole B-coefficient was extracted from the concentration dependent viscosity data to more clearly quantify the differentiation.

KEYWORDS:

  • Viscosity
  • Electrolyte Solutions
  • Salt Solutions
  • Hofmeister Series
  • Jones-Dole Equation
  • B-Coefficient

 

1. What is the Jones-Dole Equation Relationship?

The Jones-Dole equation relationship between viscosity of a solution and concentration of solute within the solution. 

Jones-Dole Equation-1

η = Viscosity of Solution

η0 = Viscosity of Solvent at Same Temperature & Pressure

A = Coefficient that explains the charge-charge interactions on the viscosity of a solution 

B = Coefficient that characterizes the solute-solvent interactions at a defined temperature & pressure

C = Solute concentrations

2. If you can do low concentrations, can you do high concentration protein measurements?

Yep! Similar to this application note, we have a number of more application notes that focus on various concentrations including higher concentration viscosity solutions. Check them out:
